Vitamin D(25-Hydroxy) & Vitamin B12

The Vitamin D (25-Hydroxy) & Vitamin B12 package helps measure the level of vitamin D and B12 in the blood and detect possible health concerns associated with vitamin D and vitamin B12 deficiency. Vitamin D helps keep bones, teeth, and muscles healthy, whereas vitamin B12 maintains blood, brain, and nerve functions.

Vitamins, although required in small amounts, are significant in maintaining your overall health and well-being. Vitamin D plays a vital role in many bodily functions, including immune system regulation, bone health maintenance, and cell growth. It is also a multifunctional hormone that regulates the levels of other nutrients, such as calcium and phosphorus. Low vitamin D levels can lead to many disorders, such as an increased risk of fractures, muscle weakness and lethargy, dysfunction of the immune system, and an increased risk of chronic diseases like diabetes. 

Vitamin B12, also known as cobalamin, belongs to the B complex group of vitamins. It is vital for making red blood cells, cell and tissue repair, and optimal brain and nerve health. Some common symptoms of vitamin B12 deficiency include weakness, mouth ulcers, appetite loss, numbness, muscle weakness, etc.

The Vitamin D (25-Hydroxy) & Vitamin B12 package can help determine vitamin D and vitamin B12 deficiencies or if you have too much vitamin D in your body (most likely from excessive supplements). This test also helps determine the response to vitamin B12 therapy in conditions like anemia. Additionally, this test is an important monitoring parameter to maintain a healthy pregnancy, as low vitamin B12 levels have been associated with adverse pregnancy outcomes like anemia, low birth weight, and growth retardation of the baby.

Usually, no special preparation is required for this test. You may eat and drink as per your daily routine. However, do let your doctor know about all the medications you take, as some of them may affect the accuracy of the test results. 

Test result ranges are approximate and may differ slightly between labs depending on the methodology and laboratory guidelines. Talk to your doctor about your specific test results. The results will help them determine your medical condition, make recommendations for lifestyle modifications such as diet and exercise, prescribe medication, if required, to manage your condition, and formulate your overall treatment plan.
