Freemartin Test available at SVS Labs. The test for Freemartinism is based on detecting male DNA in the blood of a heifer.

Marek’s mortalities. The highly contagious Marek’s disease virus is a common cause of mortality in backyard chickens – and the clinical signs are diverse and overlap with several other common conditions in poultry flocks. So what’s the best way to diagnose it?

Is that really a urinary tract infection? Urine is often submitted for microbiological evaluation when investigating lower urinary tract disease in cats and dogs. In these cases, culture should always be accompanied by a complete urinalysis including a urinary sediment examination, and ideally should only be performed on
a cystocentesis sample.

Blood smear and cytology preparations
SVS Laboratories has recently purchased the Siemens Hematek 3000 semiautomated slide staining system to improve efficiency and staining quality.

Semiautomated stainers stain the middle portion of the upper side of a glass slide, and a blood film or cytology smear prepared outside this area is not stained (see below). The unstained area starts about 13mm from the edge of the glass slide, therefore, we recommend blood films and cytology preparations are made within the staining area.

Diff Quik Stains Diff Quik (DQ) stains are commonly used in practice to examine blood smears and cytology samples. It is a three-step system using methanol as a fixative followed by an orange/eosinophilic solution then a blue/basophilic solution. Learn more about Diff Quick stains.

How to Package Samples for Delivery to the SVS Laboratories. Samples need to be packaged using the 3-layer IATA packaging system. This consists of a primary receptacle, secondary receptacle and an outer shipping container. Read more here.

Hot weather can affect your samples!

In hot weather, sample storage can produce artificial changes in CBC and biochemistry results. Centrifugation and separation of serum samples will decrease these changes and making a blood smear to accompany an EDTA sample preserves cell morphology. Store the spun serum and EDTA samples in the fridge, but leave the smear at room temperature.


Bulk Milk Sampling

The national survey of the bulk milk samples as part of response to M. bovis is underway. This is placing a great strain on the systems and resources and does take an understandable priority. We are still getting the samples for our BVD Testing Programme but we are seeing a delay of up to 2 weeks in the timing of these.

We apologise for any inconvenience caused by this and are doing all we can to turn the testing around as quickly as possible once we have the samples.

Thank you very much for your support and understanding in this matter.

Client Survey

Thank you to all those who took the time to participate in our recent client survey. The response rate was pleasing and the feedback very useful in helping us stay aligned to the service characteristics that are important to you.

It is clear that turnaround time is the leading determinant of satisfaction and it is pleasing to see a strong performance in that measure. A key factor in this area is our single location that sees all testing done at the one lab without the need to transfer samples elsewhere. This allows us, and this was borne out in the survey, that even if we are in a different region or even Island we are capable of meeting this requirement.

We have now conducted the draw and we are delighted to announce the five winners of a $100 Prezzy Card:
