PRIMA Labs Vitamin D Test Kit is a rapid self-test that can semi-quantitatively detect the presence of vitamin D in human whole blood.

Vitamin D is one of many fat-soluble secosteroids that assist in increasing the absorption of calcium, iron, magnesium, phosphate, and zinc in the body. Measuring the blood concentration of vitamin D (including both D2 and D3) is the most reliable way to assess vitamin D levels. Vitamin D3 is naturally produced when the skin is exposed to ultraviolet rays, while vitamin D2 is primarily obtained through food sources. After being produced in the skin, vitamin D is transported to the liver where it is metabolized into 25-hydroxy vitamin D.

Who should test their Vitamin D levels?

Vitamin D Test is particularly recommended for people commonly at risk of vitamin D deficiency, such as subjects with the following symptoms: frequent fatigue and tiredness, insufficient exposure to the sun, limited intake of this element through diet or who have problems in intestinal absorption.

How does it work

Vitamin D Test is an immunochromatographic device that, thanks to specific antibodies, is able to detect the levels of 25-hydroxyvitamin D in a blood sample and highlight its concentration thanks to the intensity of the Test Line (T) obtained.

This test shows results of:
– deficit 0-10 ng/ml
– insufficient 10-30 ng/ml
– sufficient 30-100 ng/ml
– excess >100 ng/ml

When should the test be done

It is useful to do the Vitamin D Test if you suffer from osteoporosis, other bone health problems or diseases that influence fat absorption (such as celiac), following particular conditions in which the absorption of Vitamin is compromised (as a gastric bypass operation) or in case of drugs that interfere with the action of the molecule (anticonvulsants and glucocorticoids).
It is also advisable to perform the Test if the calcium levels are low and/or if the patient has the typical symptoms of vitamin D deficiency, such as rickets (bone malformation in children), bone weakness or fragility and osteomalacia, repeated bone fractures in adults. Finally, the Test is also particularly suitable for people at high risk of deficiency (such as the elderly, hospitalized persons, those who leave little or nothing at home and/or expose themselves to the sun and obese people).

Result Interpretation

Excessive (> 100 ng/mL) - No clear lines appear at the test line region (T). You need to consult your doctor

Sufficient (30-100 ng/mL) - The intensity of the test line (T) is equal to or less than that of the 30 ng/ml displayed on the colour card

Insufficient (30-10 ng/mL) - The intensity of the test line (T) is darker than the 30 ng/mL line and lighter than the 10 ng/mL line displayed on the colour card

Deficit (0-10 ng/mL) - The intensity of the test line (T) is equal to or darker than the 10 ng/mL line displayed on the colour card. You need to consult your doctor.
