In the past few days, GENERI BIOTECH has been overwhelmed with inquiries regarding SRY testing — either about the availability of SRY gene detection kits or the possibility of conducting the full analysis.
We have found that the International Athletics Federation will introduce, as of September 1, 2025, a one-time test for the presence of the SRY gene, which indicates the presence of the Y chromosome. This test is a mandatory requirement for eligibility in the women’s category at competitions included in the official world rankings, such as the World Championships in Tokyo from September 13 to 21, 2025. Other women’s sports federations have quickly followed suit — we are already aware of women’s boxing, and we expect that this requirement will eventually apply to all women’s sports.
Athletes and their management teams are now under significant time pressure, as some competitions are about to begin, and although the SRY test is not technically complicated, it is not easily accessible to laypersons.
Most federations have stated that test results will be anonymized and protected, and will be shared only with the relevant sports authorities.
GENERI BIOTECH offers an SRY detection kit, but demand for it had been minimal until last week, since isolated genetic sex determination is not a common request. Typically, sex determination is a part of other tests — such as paternity or forensic analyses, and of course prenatal testing.
Testing for the presence of the SRY gene (a marker of the Y chromosome) serves exclusively to confirm an athlete’s biological sex for purposes of classification into a sporting category. It does not detect any disease, nor is it intended for treatment or prevention. Therefore, these tests are not considered part of healthcare, and are not recognized as healthcare services within the meaning of Czech Act No. 48/1997 Coll. on Public Health Insurance. This category also includes paternity tests, kinship or identity testing (e.g., in forensic science), and SRY gene tests.
Even though the test is not a healthcare service, its result is still subject to special data protection regulations under the GDPR (Article 9) — as it involves “data concerning genetic identity.”

SRY test for athletes Using the gb GENETIC SRY detection kit, we detect human male DNA present in the sample. The determination is based on quantitative real-time PCR using a fluorescently labelled probe. This test is required by the World Athletics organization and is intended for athletes in the female category in all world ranking competitions.
gb GENETIC SRY The RUO real-time PCR kit is intended for detection of the specific section of the SRY gene which is located on the Y chromosome in the human genomic DNA. Detection is based on quantitative realtime polymerase chain reaction (qPCR) using fluorescently labelled probes.
