Getting your blood test
A blood test can help refine your formula's personalisation. This guide covers preparation for the blood draw and uploading your results.
Blood testing remains optional. You can start with your health profile, then add a blood test from your member area.

The form to give your laboratory
Download the free list of biomarkers to request and their sampling requirements. You do not need an account to access the form.
Choose your laboratory
You can have your blood test at the medical laboratory of your choice. Give them the form to prepare for your blood draw.
You can also take the form to your doctor to have it countersigned. A signature box is provided on the back, so there is no need to copy out the list of biomarkers and their sampling requirements.
Prepare for the blood draw
Fasting and timing
Have your blood drawn in the morning, after a 12-hour fast. Water is allowed. Avoid coffee, tea, energy drinks and smoking before the draw, as well as alcohol during the previous 24 hours.
Physical activity
Avoid intense physical activity beyond your usual routine during the previous 24 hours. After a heavy strength-training session that is very unusual for you, wait at least 7 days before the blood draw if possible.
Sampling conditions
Aim for your usual sleep and morning routine. If you have been awake all night, have a fever or are experiencing an acute health episode, postpone the draw if possible. Sit quietly for 15 minutes before the blood draw.
Supplements and prescribed medication
To standardize your Singular blood test, pause non-prescribed dietary supplements 72 hours before the draw. Never change prescribed medication or supplements without advice from the healthcare professional overseeing them.
Menstrual cycle
If you menstruate, record the day of your cycle and whether you are bleeding. For comparable results over time, test at a similar cycle phase when possible and avoid days of heavy bleeding.
If you could not follow one of these instructions, tell the laboratory and keep a note of it when comparing your results.
Upload your results
Once your results are available, open “My blood tests” in your member area and select the option to upload a blood test.
You can check the extracted values before validating your blood test. A new validated formula applies to your next production cycles.
