High Accuracy One Step HIV Rapid Diagnostic test Cassette Certified
Whole Blood/Serum/Plasma Specimen
Product Name:
HIV 1+2 Test Device (Cassette)
INTENDED USE:
The HIV Rapid Test Cassette (Whole Blood/Serum/Plasma) is a rapid
chromatographic immunoassay for the qualitative detection of
antibodies to Human Immunodeficiency Virus(HIV) type 1 and type 2
in whole blood, serum or plasma to aid in the diagnosis of HIV
infection.Any reactive specimen with the HIV Ab Rapid Test must be
confirmed with alternative testing method(s) and clinical findings.
This test is intended for screening purposes only.
Test Principle
The HIV 1.2 Rapid Test Cassette (Whole Blood/Serum/Plasma) is a
qualitative, membrane based immunoassay for the detection of
antibodies to HIV 1.2 in whole blood, serum or plasma. The membrane
is pre-coated with recombinant HIV antigens. During testing, the
whole blood, serum or plasma specimen reacts with HIV antigen
coated particles in the test Dipstick. The mixture then migrates
upward on the membrane chromatographically by capillary action and
reacts with recombinant HIV antigen on the membrane in the test
line region. If the specimen contains antibodies to HIV 1 and/or
HIV 2, a colored line will appear in the test line region,
indicating a positive result. If the specimen does not contain HIV
1 and/or HIV 2 antibodies, a colored line will not appear in the
test line region, indicating a negative result. To serve as a
procedural control, a colored line will always appear in the
control line region, indicating that proper volume of specimen has
been added and membrane wicking has occurred.
TEST PROCEDURE
1. Bring the pouched test device to room temperature(15-30℃) prior
to testing. Do not open the pouch until ready to perform the assay.
2. Remove the test device from the sealed pouch. Lay it on a flat,
clean and dry surface.
3. Use the pipette to draw and slowly add 1 drop of whole
blood/serum/plasma to the sample well.
4. Hold the buffer bottle vertically and add 1-2 drops to the
sample well./ If using a pipette, change a new one to avoid
cross-contamination. Draw and transfer 2-3 drops of buffer to the
sample well.
5. Interpret test results within 10-15 minutes. Do not interpret
after 20 minutes.
Caution: The above interpreting time is based on room temperature
range of 15 - 30°C. If your room temperature is significantly lower
than 15℃, then the interpreting time should be properly increased
to 30 minutes.
INTERPRETATION OF RESULTS
Negative: The presence of only one line in the control region indicates a
negative result (Figure 1).
HIV-1 Positive: The control line and HIV-1 line (T1) are visible in the result
window. The test is positive for HIV-1.
HIV-2 Positive: The control line and HIV-2 line (T2) are visible in the result
window. The test is positive for HIV-2.
HIV-1 and HIV-2 Positive: The control line, HIV-1 (T1) and HIV-2 (T2) lines are visible in
the result window. The test is positive for HIV-1and HIV-2.
Regarding the positive results for both HIV-1 and HIV-2 in one
patient, it is possible for reasons as follows:
1. There is the homology in the amino acid sequence of HIV type-1
and type-2. So, it is possible that the test results show the
positive results for HIV-1 and HIV-2 in one patient,
simultaneously.
2. Provisionally, you can conclude virus type according to the line
density. If the line density of type-1 is darker than that of
type-2 in the result window, you can read as HIV-1 positive. If the
line density of type-2 is darker than that of type-1 in the result
window, you can read as HIV-2 positive. If you want to determine
virus type or co-infection exactly, you should perform the
confirmatory assay (e.g Western blot etc.).
PERFORMANCE STUDY
The HIV 1.2 Rapid Test cassette (Whole Blood/Serum/Plasma) has correctly identified specimens of seroconversion panel and has been compared to a leading commercial ELISA HIV test using clinical specimens. The results show that the relative sensitivity of the HIV 1.2 Rapid Test cassette (Whole Blood/Serum/Plasma) is >99.9% and the relative specificity is 99.9%.

Conclusion:
The sample correlation results show that the relative sensitivity of the HIV 1.2 Rapid Test cassette is >99.9%, and the relative specificity is 99.9% and the overall accuracy is 99.9% to be compared with a commercial available HIV ELISA test.
NOTE: Insufficient specimen volume or incorrect procedural techniques
are the most likely reasons for the control line failure. Review
the procedure and repeat the test with a new device. If problem
persists, please contact your local distributor.
