Frequently Asked Questions (FAQs)
Test4A is a rapid, point-of-care test that provides a quantitative measure of Vitamin A (retinol) levels in blood, using NanoSpeed’s “cube reader” technology
Vitamin A is essential for vision, immune function, skin health, and cellular growth. Deficiency can cause symptoms like night blindness, dry skin, poor wound healing, or increased susceptibility to infections. The test helps assess vitamin A nutritional status.
It is intended for adults who show symptoms or have risk factors for vitamin A deficiency (e.g. night blindness, skin issues, malabsorption disorders, restrictive diets, liver disease).
Collect a small drop of blood (finger-prick) using the lancet. Transfer the blood onto the test cassette using the pipette. Add the buffer as instructed. Insert the cassette into the cube reader. The device displays the vitamin A concentration (in µmol/L) within about 10 minutes.
The test can quantitatively measure Vitamin A in the range 0.25 to 4.0 µmol/L.
You get the result in approximately 10 minutes from applying the blood sample.
While NanoSpeed doesn’t explicitly list sensitivity or specificity on the page, the quantitative format, calibrated reader, and narrow detection range aim for precise results. However, like any diagnostic test, accuracy can depend on sample handling, timing, user error, and biological variation.
“Normal” retinol levels depend on population, age, sex, and local lab standards, but often lie within the detection range. Values below ~0.7 µmol/L are associated with deficiency in many settings. (You should compare with reference ranges used by clinical labs or public health guidelines.)
Low vitamin A suggests deficiency, which may stem from poor dietary intake, malabsorption (e.g. intestinal disorders), fat digestion issues, liver disease, or increased demand (e.g. in illness). Clinical evaluation and broader nutritional assessment will be needed.
Excessively high vitamin A levels may indicate over-supplementation, hypervitaminosis A, or disturbances in metabolism or liver storage. High levels might be harmful, so clinical correlation is essential.
