AFP tumor marker test
Alpha Fetoprotein (AFP) is one kind of main protein in embryo blood serum which blong to tumor associated antigen. The concentration range would drop to normal leval (20ng/ml) in several months postnatal in newborn serum.AFP is a single peptide chain, molecular weight is about 65000~70000. The concentration range of AFP could reach to 90~500 ng/ml in mid trimester of pregnancy.
The One Step AFP Test is a chromatographic immunoassay in-vitro diagnostic test for the qualitative detection of Alpha Fetoprotein (AFP) in human serum specimen.AFP tests are based on the principle of sandwich immunossay for determination of AFP in human serum specimen.Two monoclonal antibodies are employed to identify AFP specifically. There are two antibody bands in reaction region on the test paper : test band (T) and control band.When AFP rise beyond the normal range, a distinct pink colored band will appear in the test (T) region.
For serum, collect blood into a container without anticoagulant. Allow the blood to clot and separate the serum from the clot. Use the serum for testing.
If the specimen cannot be tested on the day of collection, store the serum specimen in a refrigerator or freezer. Bring the specimens to room temperature before testing. Do not freeze and thaw the specimen repeatedly.
When you are ready to begin testing, open the sealed pouch by tearing along the notch. Remove the test from the pouch.
Draw 0.2ml (about 4 drops) sample into the pipette, and dispense it into the sample well on the cassette
Wait 10-15 minutes and read result. Do not read results after 15 minutes.
INTERPRETATION OF RESULTS
Negative: Only one colored band appears on the control (C) region. No apparent band on the test (T) region.
Positive: In addition to a pink colored control (C) band, a distinct pink colored band will also appear in the test (T) region. Please consult your physician to perform a much more detailed exam.
Invalid: A total absence of color in both regions is an indication of procedure error and/or the test reagent has been deteriorated
