Thank you for choosing Numan. We salute your decision to take control of your health and well-being, and we will support you every step of the way.

This Safety Information Page is intended to help you make the most out of your Venous Blood Test. Please read it carefully, and do get in touch with us if you have any questions.

For this test a nurse will visit you to draw blood from a vein in your arm.
​
If this is your second Testosterone test, there must be at least 14 days gap between your first test and taking your second test, so we can confirm your Testosterone levels are consistent over time.
​
A member of our nurse network will reach out to you within 48 hours to schedule your appointment and to double check your address and contact details. Please check your profile page in your Numan account - if you need to update your phone number, let us know as soon as possible so the nurse can contact you and has the correct address for their visit.

Here are a few key things to remember to make sure you get the most out of your test:

You’ll be able to get the most accurate testosterone readings in the morning, so make sure you book between 7:00am and 11:00am.

Refrain from eating for 8 hours prior to the blood test to ensure accurate results.

Dehydration can influence the results, so make sure you drink plenty of water the night before and the morning of your test.

When your nurse arrives, they'll ask to see either a passport or a UK driving license to identify you.

Your blood test will be sent to the lab for processing, and we will notify you when the results have been sent to the Numan clinical team. This should be within three to five working days. A consultation with a Numan clinician will be scheduled with you to discuss the results of this blood test, and you will be able to discuss treatment options during this consultation. Please feel free to discuss any questions you may have with the clinician.

The venous blood test includes a PSA test, which checks the health of your prostate gland and in particular, is usually checked to monitor if someone has prostate cancer. Like with any blood test, there is always a risk of a false-positive result.

The main risk of a false-positive result is that it can lead to extra tests or medical procedures that you might not actually need. These extra tests might have their own risks, and can cause unnecessary worry and stress.

If you have any questions or concerns about the venous blood test, we're here. Just send an email to [email protected] to speak with a Numan clinician.
