Important information
Vitamin D is the term used to describe fat-soluble secosteroids that increase the intestinal absorption of calcium, iron, magnesium, phosphate and zinc. These are essential nutrients that keep the bones, teeth and muscles healthy.
The Vitamin D test is an immunoassay based on the principle of competitive binding. During testing, the specimen migrates upward on the membrane chromatographically by capillary action. The membrane is pre-coated with 25 (OH) D antigens on the test line region of the strip - the higher concentration of antigens in the specimen, the lighter would be the T line.
Reading the results
Read results at 10 minutes. Compare the T line intensity with “vitamin D colour card” provided with the kit to get the Vitamin D level in your blood. Do not interpret the result after 20 minutes.
The result will be read according to the colour card provided with the kit. To serve as a procedural control, a coloured line will always appear in the control line region indicating that the proper volume of specimen has been added and membrane wicking has occurred.
Procedure
1. Wash your hands with soap and rinse with water.
2. Open the pouch, remove the test cassette and place it on a clean and level surface. Carefully pull off and dispose of the cap of the lancet.
3. Clean your fingertip with the alcohol pad provided.
4. Press the orange end of the lancet against the fingertip. The tip retracts automatically and safely after use.
5. Keeping the hand pointing downwards, massage the end of your finger to obtain a blood drop.
6. Without squeezing the dropper, place it in contact with the blood. The blood migrates into the dropper up to the line indicated. Avoid air bubbles, you may need to massage your finger again if the blood does not reach the line.
7. Put the collected blood into the sample well of the cassette by squeezing the dropper bulb.
8. Wait for the blood to be totally dispensed in the well. Unscrew the cap of the buffer bottle and add 1 drop of buffer into the sample well of the cassette.
9. Wait for the coloured line to appear. Read results at 10 minutes. Compare the T line intensity with the vitamin D colour card provided to determine the vitamin D level in your blood. Do not interpret the result after 20 minutes.
