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

B vitamins are a class of water-soluble vitamins that play important roles in cell metabolism. Though these vitamins share similar names, research shows that they are chemically distinct vitamins that often coexist in the same foods. In general, supplements containing all eight are referred to as a vitamin B complex. Individual B vitamin supplements are referred to by the specific name of each vitamin (e.g., B1, B2, B3 etc.).

Vitamin B12 or cyanocobalamin, is a complex corrinoid compound found exclusively from animal dietary sources, such as meat, eggs and milk. It is critical in normal DNA synthesis, which in turn affects erythrocyte maturation and in the formation of myelin sheath. Vitamin-B12 is used to find out neurological abnormalities and impaired DNA synthesis associated with macrocytic anemias. For diagnostic purpose, results should always be assessed in conjunction with the patients medical history, clinical examination and other findings.

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.
