Colostrum Quality Test (Brix / IgG)

About this test
Colostrum is the thick first milk after calving. Calves are born with very little protection of their own, so the antibodies in colostrum, mainly IgG (immunoglobulin G), help guard them against early infections. Its quality varies between animals. A Brix refractometer, a small instrument that measures dissolved solids, gives a quick estimate of antibody richness, while an IgG measurement gives a more direct value. The report explains the result, which is for the owner's information. Good colostrum does not show how much the calf absorbed; a calf blood test checks that. A registered veterinarian can explain the result and advise what to do if quality is low.
How to prepare
Collect colostrum from the first milking into a clean container, mix it well, label it with the animal's name and keep it cool. The lab confirms the method, sample needs and reporting time when you book.

Before you book this test
Why this notice: so you know, before you book, how a test is done, what its limits are and who is responsible.
- Where it is tested. Some tests are done wholly or partly by an independent partner laboratory. The lab tells you before booking if this test is sent out, and the report names the laboratory that did it.
- What a result can and cannot tell you. No test is right every time. A normal result does not rule out every disease, and an abnormal result does not prove one. A registered veterinarian should read the report with the animal’s signs and history before any treatment is started, changed or stopped.
- The sample. A sample that is clotted, too small, wrongly labelled, leaking or too old may be rejected or reported with a note, and the lab may ask for a fresh one.
- Reporting time. Confirmed when you book. Times are estimates, not guarantees, and the lab confirms the time when you book.
- Emergencies. A booking or a pending report must not delay urgent care. If an animal has collapsed, struggles to breathe, has fits or bleeds heavily, call a veterinarian at once.
