Common Questions

Which labs accept Sicknote blood test referrals?

Our blood test referrals are accepted by all major private laboratories in the UK, including TDL, Spire, Sonic Healthcare, and private hospital labs such as Blackrock Clinic and HCA Healthcare.

Do I need to have seen a GP first?

No. You do not need a previous GP consultation. Our doctor assesses your symptoms directly from the questionnaire and requests the appropriate tests. Many patients use us specifically because they cannot get a GP appointment.

How long does it take?

Most referrals are reviewed and issued within 2–4 hours during business hours (Mon–Fri 9am–6pm). If ordered outside these hours, it will be ready the following morning.

Can I request specific tests?

Yes. You can specify which tests you want in the form for example, “full blood count, thyroid function and iron studies”. Our doctor will review and confirm the request is clinically appropriate before issuing.

Will my health insurer accept this?

Yes. UK health insurers AXA PPP, Bupa and Aviva accept referral letters from any GMC registered doctor. Our letters include all required details for insurance claims.

What if my referral is declined?

If our doctor determines a referral isn’t clinically appropriate for your situation, we’ll explain why and issue a full refund. Your health and safety come first.
