It is important to take your blood sample early in the morning. Samples must only be collected between Monday and Thursday and posted immediately after. This ensures your samples are not delayed in the post which will impact the stability of your samples and our ability to provide your test results. Do not collect or return your sample on a weekend or bank holiday as there will be postal delays.

If you have been asked to collect your sample on a specific day of your cycle e.g. day 3, 14, 21 but it lands on a Friday, we recommend you collect your sample the day before (Thursday). If your required day falls over the weekend, collect your sample on the following Monday and remember to post in a priority post box in time for that day’s collection.

If you have been asked to collect your sample on a specific day of your cycle e.g. day 3, 14, 21 but it lands outside the window to post samples, we recommend the following:

- On a Friday: we recommend you collect your sample the day before (Thursday).

- On a Saturday or Sunday: we recommend you collect your sample on the following Monday and advise you use a priority post box in time for that day’s collection.

No, we currently provide a self-test service only. Our kits include everything you need to take your sample in the comfort of your own home.

If you have used a Royal Mail returns label, you can track the progress of your sample here. We will also let you know via email notification once your sample has been received by our lab. Please ensure you note down your Royal Mail Tracking Number prior to posting your kit back to us, so that you can track it.

The tubes that we use in our sample collection kits contain a ingredient called an anticoagulant that ensures your sample is kept stable in transport. To ensure this ingredient works effectively, please follow the instructions in your kit closely and ensure you post your sample back to our lab Monday - Thursday.
