Komal,
One Alpha Leo is a special form of vitamin D called Alfacalcidol. This is used to treat hypercalcemia and is a special form of D used when parathyroid hormone production is low. I would trust the doctor to treat this condition. The tests scheduled are to test parathyroid hormone levels and also a clotting test (APTT). Your platelet count is low and this is the likely cause of your bruising. Please follow your doctor's recommendations, as he is trained to address these issues.
