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.



Reagents and Materials Provided

☀ Blood diluent in a dropper bottle.
☀ One sealed pouched cassette with desiccant & a disposable pipe.
☀ One piece of operating instruction with 40 test pouches.

Sample Collection and Preparation

Whole Blood ( Finger stick Specimens)

☀ Clean the area to be lanced with an alcohol swab.
☀ Squeeze the end of the fingertip and pierce it with a sterile lancet.
☀ Wipe away the first drop of blood with sterile gauze or cotton.
☀ Allow the second drop to flow directly into a sample well.

Plasma
☀ Have a certified phlebotomist collect whole blood into a purple, blue or green top collection tube (containing EDTA, citrate or heparin, respectively) by veinpuncture.
☀ Separate the plasma by centrifugation.
☀ Carefully withdraw the plasma for testing or label and store it at 4°C for up to five days. Plasma may be frozen at -20°C for at least three months.

Serum

☀ Have a certified phlebotomist collect whole blood into a red top collection tube (containing no anticoagulants) by veinpuncture.

☀ Allow the blood to clot.

☀ Separate the serum by centrifugation.

☀ Carefully withdraw the serum for testing or label and store it at 4°C for up to five days. Serum may be frozen at -20°C for at least three months.

Assay Procedure

Serum or Plasma Sample

Add 2 drops of serum or plasma into sample well. Observe the result in 120 minutes.

Whole Blood Sample

Add 1 drop of whole blood into sample well, after all blood completely absorbed. Add 2 drop of whole blood diluent. Observe the result in 20 minutes.

Storage

Store the test kits at temperature 4-30°C,in the sealed pouch for the duration of the shelf life (24 months).

Interpretation of Results

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.
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.
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.

Limitation

1. This Rapid Test is a qualitative test for the detection of anti-Tp antibody in human serum or plasma. The intensity of the test band does not correlate with the antibody concentration in the specimen.

2. A negative result for an individual subject indicates absence of detectable anti-Tp antibodies . However, a negative test result does not preclude the possibility of exposure to or infection with Tp.

3. A negative result can occur if the quantity of the anti-Tp antibody present in the specimen is below the detection limits of the assay, or the antibodies that are detected are not present during the stage of disease in which a sample is collected.
