Bovine Leukemia Virus (pooled) (PCR)

Preferred Sample

EDTA whole blood (1 ml minimum)*

*For best results, blood samples MUST be received by the laboratory within 72 hours (ideally within 48hrs) of collection. Blood samples older than 72 hours are suboptimal for testing and will be tested at Lab’s discretion. Notify the Laboratory prior to submitting large cases (>50 individuals), and these must be received by the lab prior to 10 AM to allow for same day processing.




Days Tested


Turnaround Time

1-14 business days from test day, usually within 7 business days


This targets the DNA of a portion of the pol gene from Bovine leukemia virus.



Shipping Requirements

To ensure inclusion in the test run, samples should arrive the day prior to test day. We recommend notifying the Laboratory prior to submitting large cases (>100 individuals) and to submit early in the week to allow for ample processing time.

Package samples appropriately based on weather conditions. Frozen EDTA whole blood samples cannot be tested.

Additional Instructions

Samples will be pooled by the laboratory in sequential order as listed on the Submission Form/Sample Identification Form. Broken or missing samples will not be shifted or replaced with additional samples. However, if a retest is required, you will only be charged for the actual number of retested individuals. Samples will be pooled by the laboratory in groups of 5. Retest of positive pools is $25.00 per individual sample (5 individuals per pool X $25 = $125 per retested pool).

This test is helpful to detect BLV before animals seroconvert, but not recommended as a replacement for the serology test.
