Previously named PCOS (polycystic ovary syndrome).
In May 2026, an international consensus published in The Lancet renamed PCOS to polyendocrine metabolic ovarian syndrome (PMOS) to better reflect its hormonal and metabolic effects. PMOS is one of the most common causes of irregular ovulation and infertility, affecting an estimated 6–12% of US women of reproductive age.
This at-home kit measures hormones commonly checked when PMOS (PCOS) is suspected. Your results can help you and your doctor decide on next steps. Blood results alone can't confirm PMOS: your doctor also looks at your cycle history, symptoms and sometimes an ultrasound.
PMOS is linked to a higher risk of type 2 diabetes, heart disease and high blood pressure, so it's worth talking with your doctor early.
Method:
Simple finger prick blood collection card
What does it measure?
Testosterone, SHBG, LH, Cortisol, FAI
Testosterone: Raised testosterone (androgen excess) is one of the main features doctors look for when evaluating PMOS (PCOS).
How testosterone is measured: Our lab partner measures testosterone by immunoassay, a standard lab method. Immunoassays can be less precise at the lower testosterone levels typical in women, so if your result is borderline or doesn’t match your symptoms, your doctor may recheck it with a more sensitive method called LC-MS/MS.
SHBG: Sex hormone-binding globulin carries testosterone in the blood. It is often lower in people with PMOS, which leaves more testosterone active. Very high SHBG can be related to other conditions, such as liver disease.
LH: Luteinizing hormone helps control your menstrual cycle and triggers ovulation. In some people with PMOS, LH stays consistently higher without the usual surge before ovulation, which can lead to irregular cycles.
Cortisol: Often called the “stress hormone.” High cortisol can cause symptoms that overlap with PMOS, such as irregular periods, acne and excess hair growth, so it helps your doctor consider other possible causes.
FAI: The free androgen index compares your total testosterone with your SHBG. A higher FAI can be a sign of androgen excess, one of the features used when evaluating PMOS (PCOS).
Collecting a good sample
Fill the collection area on the blood collection card completely, following your kit instructions. If too little blood is collected, the lab may report “QNS” (quantity not sufficient) and won't be able to process your sample.
Results and payment
Results are available in your private portal 2–5 days after your sample is received. This kit may be eligible for HSA/FSA reimbursement; see our FAQ for how to submit your receipt.

A portion of our revenue from each kit will be donated to fertility research and support.
