hepatitis HAV test kits

INTRODUCTION

The one step cassette style HAV IgM test is a rapid test based on the principle of immunoassay combined with conjugated colloid gold technology. The HAV test is a diagnostic device for qualitative detection of anti-HAV IgM in human serum (or plasma) specimen.

SUMMARY

In acute infection period, anti-HAV IgM is present of high level in the patients sera. The IgM antibody titer is decreased significantly and even disappeared in convalescence period, instead IgG is present. Since cases of hepatitis A are not clinically distinguishable from other types of acute viral hepatitis, a correct diagnosis can be made by blood tests which detect the specific anti-viral antibodies.

SPECIMEN COLLECTION

For serumor plasma, collect blood into a container without anticoagulant. If the specimen cannot be tested on the day of collection, store the serum (or plasma) specimen in a refrigerator or freezer. Bring the specimens to room temperature before testing.

TEST PROCEDURE

1. Dilute the serum (or plasma) specimen ***0 times with 0.*5% NaCl solution.

2. Open a pouch containing a cassette, remove the test kit from the pouch and place it horizontally on the desk.

3. Pipette 2 or 3 drops of diluted specimen into the sample well of the cassette.

4. Read results within ****5 minutes. Do not read results after *0 minutes.

INTERPRETATION OF RESULTS

Negative: Only one pink band appears on test region of the casette. This indicates that there is no detectable anti-HAV IgM in the specimen.

Positive: Two pink bands appear on test region of the cassette. This indicates that the specimen contains detectable amount of anti-HAV IgM.

Invalid: If without colored band appears on test region, this is an indication of a possible error in performing the test. The test should be repeated using a new device.
