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.
Storage
Store the test kits at temperature 4-30°C,in the sealed pouch for
the duration of the shelf life (24 months).
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.
Warning and Precautions
☀ FOR IN VITRO DIAGNOSTIC USES ONLY.
☀ All patient samples should be treated as if capable of
transmitting diseases.
☀ Do not interchange reagents from different lots or use test kit
beyond expiration date.
☀ Icteric, lipemic, hemolysed, heat treated and contaminated sera
may cause erroneous results.
Limitation
1. 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.
2. 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.
3. Some specimens containing unusually high titer of heterophile
antibodies or rheumatoid factor may affect expected results.
4. The results obtained with this test should only be interpreted
in conjunction with other diagnostic procedures and clinical
findings.
