Vitamin B12

Vitamin B12 is essential for healthy nerves and the formation of red blood cells, and a blood test shows whether your levels are adequate. It is often checked when investigating fatigue, tingling, low mood or certain types of anaemia, and is relevant for people on plant-based diets. At Centrum Medyczne Medix the test is run in the on-site laboratory at a fixed published price from a simple venous sample.

Vitamin B12 (cobalamin) is a nutrient the body cannot make for itself and must obtain from the diet, chiefly from animal-derived foods. It plays an essential role in forming healthy red blood cells and in maintaining the nervous system, so measuring the level in the blood helps establish whether intake and absorption are sufficient. Low vitamin B12 is associated with a particular form of anaemia and, over time, with neurological symptoms such as tingling, numbness or problems with balance, as well as more general tiredness and changes in mood or concentration. For this reason the test is often requested when these complaints are being investigated, and it is particularly relevant for people following vegan or strict vegetarian diets, older adults, and those with conditions or medications that can impair B12 absorption. The test uses a standard venous sample and generally needs no special preparation. At Centrum Medyczne Medix it is analysed in the centre's own laboratory at a transparent listed price, frequently alongside a complete blood count and folic acid where a clinician wants a broader view of nutritional and haematological status. The laboratory is open Monday to Friday 8:00–19:00 and Saturday 8:00–13:00; results are interpreted by your referring doctor, who will advise on supplementation or further tests if the level is outside the expected range.
