CEA Blood Test

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.

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.

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.

Another key test is the thyroid-stimulating hormone (TSH) test. TSH is produced by the pituitary gland and plays a crucial role in regulating the production of T3 and T4 by the thyroid.

If your TSH levels are elevated, it may indicate that your thyroid is not producing enough T3 and T4, which can suggest hypothyroidism. Conversely, low TSH levels may signal that your thyroid is overactive, producing excessive T3 and T4, which could be indicative of hyperthyroidism.

In some cases, your doctor may recommend additional tests, such as a thyroid scan or thyroid antibody tests, to further investigate thyroid function and diagnose specific conditions.

If your results fall outside the normal range and raise concerns, it is crucial that you contact your GP or emergency services immediately by calling 111 or 999. Please remember: if you feel unwell or are concerned about your health, do not wait for test results—reach out to emergency services as soon as possible.

Disclaimer: If your test results are abnormal, we are not responsible for follow-up treatments or for notifying a healthcare professional. By taking a test with us, you agree to take the necessary steps to follow up with a healthcare provider independently.
