Blood Test Explained
Below we have explained each inclusion.
Thyroid related blood testing
TSH (thyroid stimulating hormone) is a hormone manufactured in the pituitary gland (found in the brain). It s role is to stimulate thyroxine production in the thyroid gland (found in the neck). A high level within a health screening is associated with an underactive thyroid gland (hypothyroidism) and a low level is found if the thyroid gland is over-active (hyperthyroidism). Changes in the TSH level alone can indicate underlying thyroid problems even if the thyroxine levels are normal.
Free T4 (free thyroxine) is the active form of thyroxine, released from the thyroid gland in the neck. Its role is to control metabolism - release of energy from all cells of the body. A lack of thyroxine leads to, for example, tiredness and weight gain, whereas an excess will lead to weight loss, rapid heart rate and anxiety. It is generally believed that this level (FT4) is the most reliable indicator of thyroid status - ie whether the gland is over-active (hyperthyroidism) or underactive (hypothyroidism).
Free T3 (Free Triiodothyronine) - This is one of two hormones produced by the thyroid gland. This measures the level of T3 that is 'free' and is able to regulate metabolism.
Cortisol As Cortisol decreases TSH, thereby decreasing thyroid hormone production, as well as inhibiting T4 to T3 conversion, measuring Cortisol is important and is now included in all Blue Horizon postal Thyroid Profiles.
Magnesium is very important and relates to the Thyroid gland in many ways, in fact the thyroid cannot function without magnesium as it is responsible for helping make more T4 within the Thyroid gland. It also helps in converting inactive T4 into an active form of T3, this allows the metabolism of body cells which are enhanced by T3 (unlike inactive T4).
A deficiency in Magnesium has also been linked to goiter and/or enlarged thyroid gland.

How do you get a Blood Test?

2. Arrange your sample collection appointment/blood draw.(ensure you have checked if you need to fast before attending your blood draw)
3. Wait for your blood test results, once they’re ready we will send them to you via email within the turnaround time stated on the website.
Do I need a Doctors referral to use this service?
No you do not require a Doctor’s Referral, we provide one when you have placed an order. This is free of charge, and a consultation is not required unless stated on certain tests.
How soon will I get my blood test results?
The turnaround time is a guide only, and will sometimes depend upon assay run schedules. Most results are provided within the time frame provided, but there may be technical difficulties, or the results may need to be re-run to check accuracy, or our Doctor may be held up passing comment. We can easily give you a status report, so please do email us or phone us to chase results, not the Laboratory itself.
Where can I get my blood taken if I order a vacutainer kit?
If you do not know of a professional nurse or phlebotomist we can refer you to a BMI Hospital or arrange a *Nurse home visit (charges will apply). PLEASE NOTE: You cannot attend at a Spire Hospital or the Doctors Laboratory (TDL) for your blood draw using our kit as our postal service is dealt with by a completely separate laboratory network.
What is the difference between reported and unreported results?
1. Reported results will be sent to the GP for comment, this process can take up to two working days to complete in addition to the stated turnaround time for results.
2. If you select unreported results, then you choose not to have the interpretation of our GP and they will be sent directly to you. This is advisable if you already have a specialist to share the results with or are able to interpret them yourself. In the event of any results being of a critical nature we will always be in contact to make you aware of this.
