FAQs
Where do I send my sample?
You will receive a free return label to send your health test samples back to our lab for analysis. Clear instructions, including return details, will be provided via email to ensure a smooth and hassle-free process.
What do I need to do before my test? i.e. fast, no drinking, etc
If fasting or limiting alcohol intake is required before your blood test, we will send you personalized instructions via email after your order is placed. However, most tests can be taken without the need for fasting.
When will I get my results/how will I receive my results?
Results are typically processed within 2–3 working days. If a sample is sent over the weekend (which we do not recommend), you will receive your results within 2–3 days from the following Monday. Once your results and personalized report are ready, you will receive an email notification with instructions to log in to the Welzo online platform and view your results.
What if my results show that I’m outside the normal range?
If your results fall outside the normal range and are of concern, it is important to contact your local GP or emergency services by calling 111 or 999 immediately. Please note, if you feel unwell or have health concerns, do not wait for results—seek medical help as soon as possible.
Disclaimer: If your test results are abnormal, we are not responsible for follow-up treatments or notifying a healthcare professional. By taking the test, you agree to independently follow up with a healthcare provider as needed.
Where does my information go, and is the system secure?
Once you register with our platform, your details are securely encrypted and pseudonymized. Your sample will be sent to our lab and registered using an encrypted HL7 file (Health Level Seven International), a standard for exchanging and managing electronic health records (EHRs). To further protect your privacy, your data and sample will be pseudonymized, meaning an unidentifiable alphanumeric code will be applied to your account. This enhances the security and anonymity of your information.
