FAQs
How does a blood test work?
Check in at our clinic for your selected appointment date and time. One of our clinicians will take you through a few basic checks, before taking a blood sample from a vein in your arm. The whole process shouldn't take more than 15 minutes.
Afterwards, we'll bring you out to our waiting area, and you are welcome to enjoy a tea or coffee before going about your day. We will send your sample for analysis.
When should I book my blood test?
This blood test can be taken at any time throughout the day. It is advised that you reschedule your test if you are feeling unwell, as this can affect the results.
Do I need to prepare for a blood test?
Drinking water is encouraged. Staying well hydrated helps make the blood collection easier. On the day of your appointment, wear a loose-fitting top so your arm is easily accessible.
After booking, you will receive a pre-appointment questionnaire via email - please complete it before attending your appointment.
What do the biomarkers indicate?
Thyroglobulin Antibodies (TgAb) & Thyroid Peroxidase Antibodies (TPOAb): Autoantibodies that can indicate autoimmune thyroid conditions such as Hashimoto’s or Graves’ disease.

Thyroxine (T4, free direct) & Triiodothyronine (T3, free): Key thyroid hormones that control metabolism, energy, and overall hormonal balance; imbalances can affect weight, mood, and wellbeing.
