Low Testosterone

Low-T confirmation Venous Blood Test

Q: What is the Low-T Confirmation Venous Blood Test?

The Low-T Confirmation Venous Blood Test is a follow-up test to confirm low testosterone levels after an initial test has indicated low levels. This reading establishes a baseline testosterone and allows you to start treatment.

Q: Why do I need a second blood test to confirm low testosterone?

As per the guidelines set out by the British Society for Sexual Medicine (BSSM), you must have two blood tests to confirm a testosterone deficiency and begin treatment.This is because testosterone levels can naturally fluctuate due to factors like time of day, stress, and physical activity. A second test ensures accuracy and helps confirm whether your testosterone levels are consistently low.

Q: What additional biomarkers are tested in the Low-T Confirmation Venous Blood Test?

In addition to confirming testosterone levels, this test measures other biomarkers such as SHBG (sex hormone-binding globulin), LH (luteinizing hormone), and FSH (follicle-stimulating hormone), which help assess your overall hormonal balance and confirm suitability for TRT.

Q: How is the blood sample collected for this test?

The blood sample for the Low-T Confirmation Venous Blood Test is collected through a venous blood draw, which means blood is taken from a vein, typically in your arm, by a trained healthcare professional.

Q: Where can I get the Low-T Confirmation Venous Blood Test done?

You can have the test done at a Randox clinic, or you can book a nurse to visit your home or another suitable location to perform the test.

Q: Is fasting required before taking the Low-T Confirmation Venous Blood Test?

Yes, fasting is required before taking the Low-T Confirmation Venous Blood Test. You should avoid eating or drinking anything except water for at least 8-12 hours prior to your appointment. This helps ensure accurate measurements of testosterone and other biomarkers. Drinking plenty of water before the test helps to bring fluid to the veins, making it easier to do the blood draw.Additionally, please note that you&#39;ll only be able to book a slot before 11am, as testosterone levels are typically highest in the morning, providing the most accurate results.

Q: How long does it take to get the results of the Low-T Confirmation Venous Blood Test?

Results are available 3-5 days after the sample is collected. You&#39;ll be notified when your results are ready, and they&#39;ll be available to view via your account or the app. Through your account, you can confirm the treatment that you discussed with a Numan doctor.
