This check has been designed to start helping investigate why you are having trouble losing weight. It investigates whether this could be due to your metabolism (Thyroid), low energy, diabetes or low Vitamin D levels.
This test includes (expand individual tests for details):
HbA1c is your average blood glucose (sugar) levels for the last two to three months. High levels mean you have too much sugar in your blood. This can lead to diabetes complications, like serious problems with your eyes and feet.
Iron (TIBC included)
This test measures how much iron is in your blood. It will identify iron deficiency or iron overload. Symptoms for both include: fatigue, muscle weakness, moodiness and difficulty concentrating.
Thyroid Stimulating Hormone (TSH) is produced in the pituitary gland. It tells the thyroid gland to produce thyroid hormones (T3 & T4.) High levels of TSH indicate an underactive thyroid while low levels indicate an overactive thyroid.
Thyroxine (T4) is one of two major hormones produced by the thyroid gland (the other is called triiodothyronine (T3)). This test can tell whether the thyroid is performing properly. Thyroid hormones help regulate your metabolism (how the body functions).
Vitamin D (25 OH)
Vitamin D is a hormone which is created by sunlight on your skin. Abnormal levels of vitamin D can indicate bone disorders, nutrition problems, organ damage, or other medical conditions. Many people in the UK have low Vitamin D levels.
