A Thyroid Function Test (TFT) is ordered when imbalances in hormones are suspected, resulting in the following symptoms; - Fatigue - Weight gain - Depression - Hypersensitivity to cold temperatures - Dry skin and hair - Muscle aches - Loss of sex drive - Irregular or heavy periods - Fluid retention
A Thyroid function test includes a blood test to measure the following in a blood sample; - Triiodothyronine (T3) - Thyroxine (T4) - T3 Resin Uptake (T3RU) - Thyroid Stimulating Hormone (TSH)
We will send you your TFT blood test sample collection kit. It contains instructions with all the equipment you will need to take your blood sample in the comfort of your home. If you are unsure about a blood sample collection, you can opt for a clinic-based blood sample collection.
Your test kit includes 1st class postage and packaging for you to send your blood sample directly to our laboratory for analysis. If you want to ensure your sample arrives at the laboratory the following day itself, you may send your blood sample through guaranteed next day delivery.
Our medical team at ‘The Online Surgery’ will provide a full report of your FSH test results within four working days after receiving your sample with follow-up advice if necessary. If your TSH levels are on the higher side and you have symptoms of hypothyroidism, you are likely to have an underactive thyroid. High levels of T4 indicate an overactive thyroid. High levels of T3 indicate a high amount of oestrogen in the blood. High levels of T3RU indicate problems with the kidneys and the body not getting enough protein.
