What the GenderGP Testosterone FBC test is for
Hormone therapy can feel straightforward on paper, then confusing in real life when symptoms shift and you are not sure whether your levels match how you feel. This home blood test is designed for people using testosterone as part of gender-affirming care who want a clear, objective snapshot they can take into clinician conversations.
The GenderGP Testosterone FBC test measures testosterone alongside a Full Blood Count. In practice, that means you can see your current testosterone level, while also checking key blood measures such as haemoglobin and haematocrit. These FBC results help show how your body is responding to testosterone over time, including changes in red blood cell concentration that can matter for safer ongoing monitoring.
Testing from home can be useful when you are starting testosterone, adjusting a dose, maintaining a stable plan, or simply trying to understand a change in how you feel. It can also provide a baseline result and make it easier to track trends between appointments, rather than relying on symptoms alone.
This home test kit uses a finger-prick sample and is analysed by a UKAS-accredited laboratory, with results reviewed by a GP. The aim is clarity you can act on, with information that supports shared decision-making and more informed follow-up as part of your ongoing care.
