The kit use highly specific antigen-antibody reaction and immune chromatography methods to qualitatively
test tetrahydrocannabinol (THC),apply to the preliminary screening for drug of abuse of THC.
This kit uses specific antigen-antibody reaction, combining Gold Immunochromatography Assay experiment,
highly specific and sensitive competition method to detect the THC in urine.
When testing,urine chromatography upward by capillary action. If the concentration of THC in urine is below 50ng/mL, colloidal gold antibodies can not combine all of THC to form a purple line in the test area (T). If the
concentration of THC in urine is higher than 50ng/mL, colloidal gold antibodies can combine all of THC, so
there doesn’t appear purple line. No matter that if the THC exist in the urine, a purple line will appear in the
Procedure & Results
Read the instruction carefully before testing. Beforehand, make the test kit and sample recovered to room
temperature 15-30℃.The foil pouch can not be torn open until everything gets ready.
1. Open the foil pouch and take out the test strip/ cassette.
2. Test Procedure 2.1 Strip: Invade one end with an arrow of the strip into the container that filled with urine, take it out after 5s
and put in on a clean and flat table. Note that the liquid level of urine can’t excess the MAX line of the test
2.2 Cassette: Drop three drops (about 100uL) of urine sample in the sampling well with a pipette.
3. Read the test results within 5-10 minutes, it is invalid beyond 10 minutes.
