Vitamin D Total-25 Hydroxy Plasma/ Serum

Vitamin d blood test is done to measure Vitamin D levels in body.
Testing is required to diagnose rickets in children and osteomalacia in adults which presents as bone deformity and increase risk of fracture. Levels are also estimated to monitor vitamin D replacement therapy.
Low vitamin D levels can help diagnose a case of  secondary hyperparathyroidism.
Often Vitamin D levels are tested along with serum calcium, phosphorous, parathyroid hormone.
For patients with renal diseases 1,25 dihydroxy vitamin D should be tested

• This examination is used to gauge the body's vitamin D levels.
• Rickets, which manifests as bone malformation and raises the risk of fracture in youngsters, and osteomalacia, which does the same in adults, must be diagnosed through testing.
• Estimated levels are used to track vitamin D treatment.
• Secondary hyperparathyroidism can also be identified by low vitamin D levels.
• Testing for 1,25 dihydroxy vitamin D must be done in patients with renal disorders.

Vitamin d blood test measures level of 25 hydroxy vitamin D total

During a vitamin d blood test, a health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out. This usually takes less than five minutes.

Low levels of Vitamin D are associated with  osteoporosis, bone weakness and increased chance of fractures. Severe deficiency can lead to Rickets and osteocalcin.
Very high levels are associated with nausea, vomiting, poor appetite, constipation, weakness

Checking vitamin D 25 (OH) levels is recommended for those getting treatment to prevent or treat osteoporosis, exhibiting symptoms of low calcium levels (hypocalcemia), or having high calcium levels (hypercalcemia).

The major function of vitamin D is to assist in controlling the body's phosphate and calcium levels. These nutrients are essential for maintaining strong bones, teeth, and muscles. The majority of the vitamin D you require can be obtained by regular exposure to sunlight. Our diet is the other major source of vitamin D. The 25-hydroxy vitamin D screening test is the most precise method of determining the amount of vitamin D in your body.

Patients receiving treatment to avoid or treat osteoporosis, those exhibiting indications, and signs of insufficient calcium levels (hypocalcemia), or excessive calcium levels should have their vitamin D 25 (OH) levels checked (hypercalcemia).

It is based on the signs and symptoms you display and the discretion of your doctor.

You will not be permitted to eat anything between four and eight hours before the test, according to your doctor.

The body receives vitamin D from cutaneous production and dietary intake; the closest indicator of this is currently thought to be the total serum 25(OH)D level. The total 25 (OH)D level reference range is 20–100 ng/mL.

The limited hazards associated with the 25-hydroxy vitamin test are as follows:

• heavy bleeding.
• dizziness.
• a slender probability of infection at the site of the needle prick

Children who have rickets have weakening and thinning of their bones, which is typically caused by a severe and sustained vitamin D deficit. Rickets can also occur due to uncommon hereditary issues.

It is a common practice to test serum calcium, phosphorus, and parathyroid hormone in addition to vitamin D levels.
