How can we help?

Can I collect my sample if I am taking medication or supplements?

Medication & Antibiotics 

If you are taking any medications or antibiotics, please provide what supplements or medications you are taking on your profile so our doctors can take this into consideration when reviewing and commenting on your results. 

Antibiotics may affect your results. It would be best to complete your prescribed course and wait at least one week before testing. 

It’s always best to check with us first if you are on any medication by contacting [email protected]. Our customer service team is available from 9.00 am to 5.00 pm Monday to Friday (excluding bank holidays) and aims to respond within two working days.

Recent Infections Or Vaccinations

We recommend waiting one week after infection or vaccination of COVID-19, as this can provoke an immune and inflammatory response which can affect your results. 

Supplements

You can still take the test if you are taking supplements. Your result may help you ascertain if you need to increase or reduce your dosage. We recommend you collect your blood sample while following your usual routine. 

If you would like to know what your baseline level would be without taking supplements then we recommend that a period of 6 weeks elapses from your last supplement to taking the test.

If are taking supplements when taking the test, we ask that you provide this information on your profile.
