Treponema Pallidum(TP) Rapid Diagnostic Kit (Colloidal Gold)
For the qualitative detection of Syphilis antibodies in
serum/plasma and whole blood
Intended Use
The Syphilis Rapid Diagnostic Test is a qualitative test for the
detection of antibodies to Syphilis in human serum/plasma and whole
blood. It is considered as an initial screening test for Syphilis
antibodies. All positive specimens must be confirmed with Western
Blot or other qualified EIA.
Principle
Syphilis Rapid Diagnostic Test is a chromatographic immunoassay
(CIA) for the detection of antibodies to Syphilis in human serum or
plasma. Syphilis 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 Syphilis specific
antigens. Antibodies to Syphilis, if present, a red colored band
will develop on the membrane in proportion to the amount of
Syphilis 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, a red colored
band in the control region will always appear regardless the
presence of antibodies to Syphilis. The RDT is simple, rapid,
sensitive and specific.
Direction of Use
A. For Whole Blood specimen:
1. Dispense 1 drops of Whole Blood specimen to the “s” well of the
test card with the provided plastic dropper according to the
figure.
2. Add 1 or 2 drops of Sample Diluent to the sample well,
immediately after the specimen is added, from the dropper tip
diluent vial (or all contents from the single test ampule).
3. Interpret test results in 20 minutes.
B. For serum or plasma specimens:
1. Dispense 2 or 3 drops (100 μl) of serum/plasma specimen to the
“s” well of the test card with the provided plastic dropper
according to the figure.
2. Start the timer and wait for the colored line(s) to appear.
3. Interpret test results in 20 minute.
Interpretation of Results:
1. Negative: No apparent band in the test region (T), Only one red band appears
in the control region (C). This indicates that no TP antibodies
have been detected.
2. Positive: In addition to one red band in the control region (C), a red band
will appear in the test region (T). This indicates that the
specimen contains TP antibodies.
3. Invalid: If no band appears in the control region(C), regardless of the
presence or absence of band in the test region (T). It indicates a
possible error in performing the test. The test should be repeated
using a new device.
Note:
1. Must use fresh specimen and avoid repetitive freezing, the
result will be invalid
2. Use it before expiry date.
3. The package of kit should not be opened until it reaches the
room temperature if it taken out from the refrigerator.
4. Old Serum can not be used. If the serum is thick, it can be used
only after being separated.
Storage
Store the test kits at temperature 4-30°C,in the sealed pouch for
the duration of the shelf life (24 months).
