PRIMARY SAMPLE : SERUM
Vitamin D is a precursor of the steroid hormone 1,25-(OH)2D3 which binds to and activates the transcription factorVDR (Vitamin D receptor).The vitamin D-VDR complex regulates2-3% of the human genome and thus has a major influence on the human organism. Skin exposure to ultraviolet (UV) radiation from the sun is the main source of vitamin D. Sources of vitamin D in the diet include fatty fish such as herring and salmon. Vitamin D Insufficiency Vitamin D deficiency is a major global health problem. Several population studies have identified widespread 25-OH insufficiency in apparently otherwise healthy populations.Indication of Vitamin D measurement
Suspicion of vitamin D insufficiency/ Pregnancy/ Liver diseases/ Kidney diseases/ Estimation of the cardiovascular risk/ Determination of the nutrive/vitamin D status/ Suspicion of Vitamin D-Intoxication

REFERENCE RANGE IN PREGNANCY:
Low TSH blood test results indicate an underactive thyroid gland, that is, hypothyroidism. This means that the thyroid gland is not producing thyroid hormones to the optimum level. The pituitary gland releases more TSH hormones to stimulate the thyroid gland to produce more hormone. A high TSH level indicates some acute or chronic problems related to thyroid dysfunction. High TSH blood test results also indicate that there may be some problem with the pituitary gland. A tumor may cause high TSH levels to be secreted by the pituitary gland. Patients who have undergone thyroid gland removal surgery may also show high TSH blood tests results. This means they are not begin administered the correct dose of thyroid medication that keeps the hormone production in check. You can read more on blood test results explained.High TSH blood test results indicate an overactive thyroid gland, that is, hyperthyroidism. Also, low TSH blood test results indicate a patient is begin administered excessive doses of thyroid hormone medication, in case of hormone replacement therapy. In very rare cases, low TSH level indicate towards damage or problems with the pituitary gland.
