Sample Identification and Shipping


Tube numbers should be easily distinguishable from animal ID numbers (underline, circle, or use different color ink for tube numbers). Be legible to avoid a zero looking like a six, a four looking like a nine, etc.

Tubes should be numbered to indicate order on chart and be in consecutive order, e.g., 1 thru 10, or 21 thru 60, etc.

If samples from several sites or farms are sent to the lab in the same package, label tubes so it is clear whose samples are whose. The preferred method is to label all tubes with different numbers, e.g., Farm A, #1-10; Farm B, #11-40.

Use permanent ink. Water soluble ink may smear when moisture condenses on cool tubes.


Please send tubes in a box with dividers, organized in chart order. To prevent leakage, push down on plastic tubes so that the cap lip is not stuck on the divider top. DO NOT SEND TUBES IN A BAG; they may leak because the caps loosen, or break. It also takes the lab much longer to organize them for testing.

Ship overnight. Protect from freezing in winter and heat in summer.

Submission Forms

Standard Minnesota Board of Animal Health Test Charts should be used with the actual signature of the veterinarian that drew the blood. Click here to download submission forms.

If Brucellosis testing is required, include either the Federal Brucellosis Form, or copies in triplicate of the BAH Test Chart already prepared, with tests requested.

When testing for FAA and 4-H exhibitions, provide a separate test chart for each owner. If tubes from several farms are sent together in the same package, label the tubes with consecutive numbers to prevent confusing tubes between farms.
