The Blood Stain Rapid Test Dipstick (Stain) is a rapid chromatographic immunoassay for identification of human blood in suspected stain.
The Blood Stain Rapid Test Dipstick (Stain) is a qualitative, lateral flow immunoassay for identification of human blood in a suspected
stain. The membrane is pre-coated with anti-hemoglobin antibodies on the test line region. During testing, the specimen reacts with the
particle coated with anti-hemoglobin antibody. The mixture migrates upward on the membrane chromatographically by capillary action to
react with anti-hemoglobin antibodies on the membrane and generate a colored line.
How to use?
Allow the test, specimen, buffer and/or controls to reach room temperature (15-30°C) prior to testing.
1. Bring the pouch to room temperature before opening it. Remove the test Dipstick from the sealed pouch and use it as soon as possible.
2. With arrows pointing toward the mixture solution, immerse the test dipstick vertically into the mixture solution for 10-15 seconds.
DO NOT PASS THE “MAX” LINE on the lower strip label of the dipstick
when immerse the dipstick.
3. Place the dipstick on a level and clean desk, start the timer and wait for the color line (s) to appear. Read the result at 5 minutes, do not interpret the result after 10 minutes.
INTERPRETATION OF RESULTS
POSITIVE:* Two lines appear. One colored line should be in the control line region (C) and another apparent colored line should be in
the test line region (T).
*NOTE: The intensity of the color in the test line region (T) will vary depending on the concentration of human semen present in the
specimen. Therefore, any shade of color in the test line region (T) should be considered positive.
NEGATIVE: One colored line appears in the control line region (C). No line appears in the test line region (T).
INVALID: Control line fails to appear. Insufficient specimen volume or incorrect procedural techniques are the most likely reasons for control line failure. Review the procedure and repeat the test with a new test.
