3.4.3     HAEMATOLOGY AND BIOCHEMISTRY SAMPLES     Haematology - Sample Type

·      Haematology testing is performed on EDTA (purple top tube) anticoagulated blood.

·      EDTA tube should ideally be more than half full.

·      Ensure that the blood is mixed promptly with the EDTA to avoid sample clotting. This should be done by rolling the tube between your palms or gentle inversion several times. Do not shake the tube.

·      If there is going to be a delay between sample collection and submission, always make 2- 3 blood smears from the sample and submit with the EDTA tube.

·      EDTA blood should be kept refrigerated but kept out of direct contact with the icepack (insert paper towels between blood tube and icepack).

·      Direct contact cause hemolysis.     Biochemistry and Hormone - Sample Type

·      Sample should collect in a plain tube or clot activator tube (red or yellow top tube).

·      Allow blood to clot at room temperature for 30 minutes.

·      If there is any delay between sample collection and submission, then centrifuge and separate serum from the clot and decant into a new plain tube prior to sending. Presence of red cells may artefactually alter results.     Fibrinogen - Sample Type

·         Sample should be collected in Sodium Citrate tube (light blue top).

·         Mix well immediately after collection.

·         Sample must be free of clots.

·         If there is any delay between sample collection and submission, the sample must be centrifuged and transfer the plasma to an additive free tube and freeze.

3.4.4     PATHOLOGY     Carcasses for necropsy/Postmortem

·      A fully completed CVRL requisition form must accompany all carcasses submitted to CVRL: CVRL will not perform necropsy without the PM-requisition-form, which is mandatory to gather the information needed before doing the necropsy.

·      Please provide the microchip-number/ring number as we cannot identify any animal by name.

·      CVRL must be notified in advance of any suspected cases of highly contagious or zoonotic diseases such rabies, tuberculosis, brucellosis, influenza, and on the requisition form this information must be clearly specified.

·      If transport is delayed for one or two days, keep pets, birds and small animals in bio-hazard bags in the chiller.

·      If transport is delayed for several days, freeze pets, birds and small animals in bio-hazard bags. However, necropsy and histopathology will be compromised due to freezing artefacts.

·      Large animals must be transported immediately to CVRL for necropsy to avoid autolysis.

·      CVRL can provide transportation of large carcasses in CVRL’s leakproof truck, if needed (with extra charges).

·      For bio-security reasons’ NO carcasses/ sample pieces can be returned, only ash.

·      Disposal is included in the necropsy. Hence, no need to fill the cremation form if no ash needs to be returned.

·      Any suspicion for fracture/ bone problems has to be mentioned on the requisition form, because CVRL cannot remove the skin from every animal requested for PM.     Histopathology samples

·         Please provide full history: gender, age, breed; location, duration, size, type of the lesion and for cytology testing, the exact site/origin of the sample must be indicated!

·         Don’t squeeze large samples into a too narrow tube: we often have to destroy the tube to get the samples out! Use leakproof tubes.

·         The ratio of tissue volume to formalin should be at least 1 to 3. Particularly for brain tissues.

·         Several brain locations are needed for proper CNS-diagnosis: stem, cerebellum, hippocampus: ½ of the brain (split longitudinal) should always be sent for histology.

·         Please cut samples larger than 2 cm in half-pieces to avoid artifacts.

·         Please cut intestinal segments open before fixation.

·         Uterine biopsies should be immediately fixed: best in Bouin’ fixative.

·         Samples to confirm gout should be fixed in 95% ethanol, because urate dissolves in formalin.

¾       Histology is always compromised due to freezing artifacts.

¾       Smears/slides should be fixed in 95% ethanol. Please use proper transport-boxes to protect your samples.     Carcasses for cremation/Incineration

·      All carcasses submitted to CVRL for incineration must accompany a fully completed CVRL –cremation form.

·      If transport is delayed for several days, freeze pets, birds and small animals in bio-hazard bags.

·      Carcasses may be delivered in batches, but CVRL needs to be informed well in advance by e-mail under cvrl@cvrl.ae 

·      CVRL can provide transportation of animals if needed, with extra charges.

·      For cremation the requisition form should clearly specify the type of ashes returned from the incinerated animals.


·      Use sterile container for samples like faeces, urine, exudates, skin scrapings and hair pluck. Sterile containers are available at CVRL.

·      Use EDTA tube for blood parasites examination.

·      Worms for identification should be sent to the lab within 24 hours using sterile containers containing PBS/saline or in 70% alcohol in case of delay of more than 24 hours.

·      Arthropods for identification should be sent in sterile container without any liquid if delivered to lab the same day and with 70% alcohol in case of delay of more than 24 hours.

3.4.6     SEROLOGY SAMPLES     General guidelines

·         Label sample container with the animal’s name using a waterproofed marker.

·         Submit sample properly filled-in laboratory requisition form. The information should include owner, species, sex, animal identification, clinical signs, previous treatment /vaccination (if any), and morbidity/mortality in the group as well as email and telephone numbers.

·         The requisition forms can be downloaded from the link Haematology Biochemistry, Serology and Analytical Chemistry Requisition Form https://www.cvrl.ae/downloads.php or https://www.cvrl.ae/cvrl-pdf/import%20specimen%20advice.pdf (in case if it is import export of equine).

·         If serum samples are heat inactivated, it should be mentioned specifically.

·         Events where the test information is incomplete or unclear, CVRL will freeze the samples and shall begin with processing only when proper information is received form the sender.     Sampling for RBT/SAT/CFT/ELISA/AGID testing    Samples brought by road the very same day:

·      Blood needs to be collected up to 3/4th level of red cap/clot activator tube (the tubes can be collected from CVRL reception desk) and allowed to settle at room temperature to achieve complete clot formation and then transported in the cool box (tubes should not be frozen and shall not be exposed to extreme temperatures). Incomplete clot formation will cause the serum to gel, due to fibrin formation.    Samples shipped to the lab:

·      Samples should be collected as described for clinical chemistry tests and must be hemolysis free.

·      After collecting the blood sample (in a serum separating tube), the serum should be spun and separated from the clot. At least 5-7 ml serum should be transferred to leak proof plastic tubes for each specimen.  Lesser amounts will not be accepted.

·      Serum must be clear: lipemic or grossly hemolyzed will not be accepted and the separated serum can be stored in cool conditions.

·      Securely attached labelling must be clear and must include the animal’s name or microchip number/ring number.

·      The samples should reach CVRL in cool condition. Samples should be packed in a leak-proof bag and then placed in a styrofoam box (see below picture) or a container (along with cool elements (see below picture) that are pre-frozen), which can withstand long shipment cycles. Do not fill in the container with ice cubes or frozen plastic water packets as it will spoil the sample containers and labelling on the tubes.

3.4.7     TAXIDERMY

·        Specimens for taxidermy need to be fresh, chilled or frozen; packed in leak proof containers or bags. Accompanied by the general requisition form with clear instructions for the required process.

3.4.8     VIROLOGY SAMPLES     General Sampling

·         All samples submitted to CVRL must accompany a fully completed CVRL requisition form pertaining to the tests.

·         Blood, swabs or tissue samples must be collected during the early stages of infection.

·         Since autolysis inactivates many viruses, samples should be taken immediately after death of the animal. Selection of areas of large organs, such as the lung, liver, and brain are important, as areas of normal tissues are often non-productive specimens for virus isolation.

·         Samples should be collected from the active edge of a lesion where high concentration of virus is usually found.

·         If the disease process primarily involves the skin or contain mucosal lesions, specimens should include vesicular fluid and epithelium overlying vesicle, scrapings of lesions and biopsies from the margin of the lesions.

·         For pox viruses, scabs or recently developed lesions from different sites of the body can be removed with a forceps or other blunt-tipped sterile instrument.

·         Samples for virus isolation must be transported in viral transport medium, which can be collected from CVRL.

·          All specimens should be kept cold (2° to 8°C) until they can be transported to CVRL.     Specimen Collection for Rapid Test for Influenza A

·         Acceptable specimens for testing include nasopharyngeal washes/aspirates, nasopharyngeal and throat swabs.

·         Excessive nasopharyngeal wash volumes should be avoided as it may result in decreased test sensitivity.

·         All samples should be collected in viral medium provided by CVRL and should be transported as early as possible to the laboratory.

·         In case of delay, specimens in transport medium may be stored at 2-8°C for up to 72 hours or at –20°C for up to 7 days.     Samples for Rabies Immunofluorescence Test (IFT)

·         Samples must be sent in a leak-proof rigid container.

·         Selection of material for Rabies testing can be the entire carcass, entire head or portion of the brain.

·         If only the brain is submitted, samples must include parts of cerebellum, hippocampus and brain stem.

·         Samples must be kept refrigerated until time to deliver to the laboratory and do not freeze the samples.     Semen sampling for Equine Arteritis Virus isolation

·         Virus isolation is usually carried out from the semen of serologically positive stallions to EAV (VNT titer: ≥1/4) which are not vaccinated against EVA.

·         It is recommended to have two samples, which can be collected (a) on the same day, (b) on consecutive days, or (c) after an interval of

·         several days or weeks.

·         It is essential that the samples must contain the sperm-rich fraction of the ejaculate.

·         Usage of antiseptics/disinfectants must be avoided during sample collection as it can inactivate the virus.

·         The semen should be refrigerated immediately after collection for transport to CVRL with a minimum of delay. If delay occurs, semen should be frozen at or below –20°C for a short period before being dispatched to CVRL.


·            Details about the tests and guidelines for submitting samples can be found on our website at the link https://www.cvrl.ae/pettravelcharges.php 


3.5.1     General

·        Deliver all specimens to the laboratory as soon as possible after collection.

·        Samples should be transported at the temperature specified in section ‘submission of samples (3.4)’.

·        The customers are also instructed on the choice of correct transport media and containers by CVRL staff as well as specified in section ‘submission of samples’ (3.4).

3.5.2     Packaging and mode of transport

·        In order to protect specimens during transport and prevent contact with the public and the environment, we recommend using the following, at least 3-part packaging system.

¾       A primary leak-proof container (specimen collection container).

¾       A secondary leak-proof container (re-sealable plastic bag) to contain any leakage in the event of damage.

¾       A rigid outer packaging (specimen transport box) to protect specimens from damage if package is dropped.

·        Specimens must be packed carefully to avoid breakage or leakage of the content.

·        Ensure all container lids are tightly closed before packaging.

·        For samples arriving from overseas, in order to have a hassle-free customs clearance at Dubai airport, the parcel should accompany CVRL import permit. This permit can be downloaded from our website and the link is: http://www.cvrl.ae/cvrl-pdf/imp_permit.pdf   

·        The samples should reach CVRL in cool condition; but use of dry ice is not recommended as it will change the category of the consignment to a higher level of inspection at customs.

·        Use ice packs to assist in maintain temperature.

·        Since CVRL doesn’t have any clearing department, it is highly recommended to use courier services like FedEx, DHL, UPS or Aramex, who will deliver it to our door.


·         CVRL MUST be notified in advance before submitting high risk samples (e.g. Rabies, Anthrax, Brucellosis, Tuberculosis).

·         It is the responsibility of the person/veterinarian making the request for testing, to ensure that both the form and the sample are properly labelled as ‘Danger of Infection’ or ‘Biological Hazard’. Alternatively, it is acceptable, both the form and the sample with an appropriate ‘Danger of Infection’ or ‘Biological Hazard’ label (as shown below).

·         The transport bag must be sealed. The form MUST NOT be placed in the bag with the sample.

CVRL reserves the right to reject samples submitted if the sample received does not satisfy CVRL conditions and requirement for testing.


Turnaround time indicates the customer the usual number of working days required to complete the requested tests and reporting the results. In general, turnaround time for each test is given in our website: http://www.cvrl.ae/services.php


Samples submitted, if remaining after testing and if practical will be retained in laboratory under appropriate conditions. Any such information can be obtained from CVRL through emails.

It may be possible to add additional tests or investigations to the original request by contacting the laboratory and submitting a completed requisition form.

·         Any request for change of test or addition of new tests after the commencement of job and before the release of the report can be added to the already submitted requisition form by submitting a new amended requisition form and the notification can be sent via email. All tests will be considered as one consignment.

·         Any request for change of test or addition of new tests after release of report will be accepted upon submission of a new requisition form with same animal details and sample collection date.

·         Any request for change of information to the already submitted requisition form before release of report can be amended by sending a mail notification and by submitting a new requisition form with the amended information.

·         Acceptance of the additional test requested for samples already received in the CVRL depends on:

¾       The request made within the appropriate timeframe.

¾       The availability of the appropriate sample.
