Intended Use
The HIV-1/2 Rapid Diagnostic Test (RDT) is a qualitative test for
the detection of antibodies to Human Immunodeficiency Virus type 1
and 2 (HIV-1/2) in human serum/plasma.
It is considered as an initial screening test for HIV-1/2
antibodies. All positive specimens must be confirmed with Western
Blot or other qualified EIA.
Principle
HIV-1/2 RDT is a chromatographic immunoassay (CIA) for the
detection of antibodies to HIV-1/2 in human serum/plasma. HIV-1/2
specific antigens are precoated onto membrane as a capture reagent
on the test region.
During the test, specimen is allowed to react with the colloidal
gold particles, which have been labeled with HIV-1/2 specific
antigens. Antibodies to HIV-1/2, if present, a red colored band
will develop on the membrane in proportion to the amount of HIV-1/2
antibodies present in the specimen.
Absence of this red colored band in the test region suggests a
negative result. To serve as a procedural control, red colored band
in the control region will always appear regardless the presence of
antibodies to HIV-1/2.
Materials Required But Not Provided
☀ Timer or stopwatch
☀ Biohazard disposal container
☀ Blood collection devices, for the testing of venous whole blood,
serum or plasma
☀ Disposable gloves
For finger stick samples, the following materials are required:
Alcohol pad
Sterile lancet
Sterile gauze or cotton
Reagents and Materials Provided
Each kit contains:
☀ 40 test cassettes(individually pouched)
☀ One bottle of diluent buffer(5ml)
☀ 40 disposable plastic droppers
☀ Each pouch contains one cassette with one desiccant bag
☀ Instruction for use
Assay Procedure
☀ Place the test cassette on flat surface. Before unseal the
pouch, allow the test cassette to reach room temperature(4-30°C)
.Use it immediately once unsealed.
☀ Open the pouch and add1drop(30-40uL) of specimen into the
sample well(S) .
☀ When the specimen is completely absorbed, slowly
add1drop(45-55pL) of diluent buffer vertically into the sample
well(s) .
☀ Avoid dropping specimen or diluent buffer in the observation
window.
☀ Do not allow the diluent buffer bottle touch the sample well
when dropping the diluent buffer so as to prevent the cross
contamination with the specimen.
☀ Observe the result between 15-30 minutes after the diluent
buffer added.
Interpretation of Results
☀ Negative: No apparent band in the test region (1 and 2), only one red band
appears in the control region (C). This indicates that no HIV1/2
antibodies have been detected.
☀ Positive: In addition to the band in the control region (C), other one or two
red bands will appear in the test region (1 and 2). This indicates
that the specimen contains HIV1/2 antibodies.
☀ Invalid: If no band appears in the control region(C), regardless of the
presence or absence of line in the test region (1 and 2). It
indicates a possible error in performing the test. The test should
be repeated using a new device.
Storage
Newscen HIV(1+2) Antibody Rapid Test can be stored at room
temperature(4-30℃, do not freeze) for 24 months from the date of
manufacture.
Keep the test cassette in sealed pouch until use.
Once you have taken the test cassette out of the pouch, perform the
test as early as possible(within 1hour) to avoid test cassette from
becoming moist. Do not use the test beyond the indicated expiration
date.
The diluent buffer should be stored at room temperature(4-30℃, do
not freeze) .
Warning
For Invitro Diagnostic Use ONLY
Read the package insert completely before use. It is very important
that the correct procedure is followed. Fail to add the patient
sample may lead to a false negative result (i.e.a missed positive)
.
