In many species, looking at an individual does not reveal the sex. In e.g. birds, males and females show no differences that may be used to identify the sex of a bird. Sex determination is based on a DNA test, in which the sex chromosomes (X, Y in animals and humans and W, Z in birds) are visualized. The DNA test reveals the sex of most species.
Test specific information
For most species the sex remains the same during life.
The Turnaround Time (TAT) depends on various factors, such as the shipment time of your sample to the test location, the test method(s) and whether the tests are performed completely or partially by a Partner Lab or Patent owner.
The TAT of tests performed at our facilities is normally 10 working days after receipt of the sample at the testing laboratory (VHL, VHP or Certagen). For tests performed by a Partner Laboratory (so-called "partner lab test") or patent owner, the TAT is at least 20 working days after receipt of your sample. Because the shipment time to our Partner Labs or patent owner may vary due to factors we cannot influence, the mentioned 20 working days are therefore an estimate.
Sometimes it is necessary to re-run your sample. We call this a retest. In that case, the TAT will of course be extended.
Location of disease or trait
All cells with a nucleus contain the same sexchromosomes.
For this test samples from all breeds are accepted.
For this DNA test we accept the following materials: Feather, Blood EDTA, Blood Heparin, Tissue. Please contact Dr. Van Haeringen Laboratorium if you wish to submit other material as listed.
The result of a sex determination shows, which sex an animal has.
The sex is inherited via sex chromosomes.
Severity of Disease
Sex determination is no disease.
