One Step HBsAb test
Casstte
INTRODUCTION
One Step Cassette Style Anti-HBs Test is
a rapid direct binding test for the visual detection of
antibodies to hepatitis B surface antigen (anti-HBs) in
serum as an aid in the diagnosis of hepatitis B
infection. One Step Anti-HBs Test is based on the principle
of sandwich immunoassay for determination of anti-HBs in
serum.
Purified recombinant antigens are
employed to identify anti-HBs specifically, This one step
test is very sensitive and only takes about 10-20 minutes.
Test results are read visually without any
instrument.
SPECIMEN COLLECTION
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.
TEST PROCEDURE
1.When you are
ready to begin testing, open the sealed pouch by tearing
along the notch. Remove the test from the pouch.
2.Draw 0.2ml
(about 5 drops) sample into the pipette, and dispense it
into the sample well on the cassette.
3.Wait 10-20
minutes and read results. Do not read results after 30
minutes.
INTERPRETATION OF
RESULTS
*Negative: Only
one colored band appears on the control region(C). No
apparent band on the test region(T).
*Positive:
In
addition to a pink colored band, a distinct pink colored
band will also appear in the test region.
*Invalid:
A
total absence of color in both regions is an indication of
procedure error and/or that test reagent deterioration has
occurred.
STORAGE AND
STABILITY
The test kit can
be stored at room temperature (18 to 30℃)
in the sealed pouch to the date of expiration.
The test kit
should be kept away from direct sunlight moisture and heat.
