More Details

Vitamin D2 is derived from fungal and plant sources, and is commonly found in supplements, such as multivitamins, in the U.S. Vitamin D2 may also be used in the pharmacological treatment of Vitamin D deficiency. Vitamin D3 is derived from animal sources and is made in the skin following exposure to sunlight. The LC/MS/MS technique is able to directly quantify Vitamin D2 and Vitamin D3. By comparison, immunoassay-based Vitamin D tests can only indirectly measure Vitamin D2 and Vitamin D3.What all does a Vitamin D3Test Cover?

Vitamin D3, commonly known as the “sunshine vitamin,” is cholecalciferol (coal’-i-kal-si’-fer-ul). It is either manufactured by the skin from sunlight (or the right tanning lamp) or provided as either a supplement or, modestly, by diet.

Cholecalciferol is converted by the liver into a pre-hormone called Calcidiol (cal-si-die’-ol) that is then stored for use by various organs in the body. This is the substance that you want to obtain a measurement of when you order a Vitamin D3 test. The proper test is called 25(OH)D and measures the blood level of Calcidiol. The test name comes from its chemical name, 25-hydroxyvitamin D.

Calcitriol (cal-si’-tree-ol) is a hormone manufactured from Calcidiol body stores. It is known as activated vitamin D and is measured by a test called 1,25(OH)D (from it’s chemical name, 1,25-dihydroxyvitamin D.) The reason this test is not meaningful for our purposes is that the kidneys will first use as much calcidiol from the body stores as is necessary to get calcitriol levels in the blood raised to the level necessary for maintenance of blood calcium levels. After the kidney has used whatever calcidiol it needs to maintain proper blood calcium levels, then the remaining calcidiol body stores are available be used by other organs in the body. If one is deficient in calcidiol, the blood level of calcitriol might still be within normal ranges, as it is produced first because sufficient blood levels of calcitriol are necessary to maintain essential levels of blood calcium. For our purposes, we are concerned with how much calcidiol is still available after the kidney has taken its share.

Fasting is not necessary to obtain a vitamin D level; however, getting blood tests at the same time makes sense, reducing the burden of time on the patient.

NABL stands for National Accreditation board for Testing and Caliberating Laboratories is the highest Quality Accreditating Body in India. It Annually Audits the Testing Labs for basic standard procedures which ensures quality of the test results. Some of these standard procedures include

Caliberation– Regular and timely Caliberation of  machines, the reagents of all tests, small instruments such as temperature recorder, microscope etc.

Controls – The Reagents of all tests under the NABL scope need to be tested at least once every day whether they are sensitive to both Positive /negative OR High/Low values. In simple words we need to test if our machine/reagents are able to detect normal and abnormal values with a corresponding predefined sample for us to be sure that our system is working fine and this we have to test everyday before we begin testing for real patients

Temperature logs – We have to maintain daily logs of temperature recordings every 2 hour of the room, storage refrigerators and more to be sure if an ambient temperature has been maintained for testing.

Customer Experience Process– We have to train our staff with an appropriate process of registring, handling, sampling and reporting of customers so that the whole process is easy and relaxed for the customers.

Contingency Training – The Staff has to be trained regarding contingency processes such as if a patient faints while drawing blood or if we encounter critically high value of some tests for which the patient or attendant need to be informed Immedietly. We have to maintain Documentation of such incidents with proper course of action for it to be audited by the NABL body.

Yes, we do have on-Board General physician and other specialists with us. We can arrange an appointment with the particular doctor of your choice to take a corrective or preventive action post your test results.
