The standard kit size of this Treponema Pallidum (Syphilis) Cassette test kit is 25 tests per box; 40 boxes per carton.

To save freight cost, sometimes bulk packing is used, meaning test strip, cassette or multi-test panel is packed in single aluminum pouch; 50 or 100 pouches in one plastic bag; and then plastic bags are packed in cartons along with the unfolded boxes for the test kits. In this way, the customers can easily pack the tests into test kits after receiving the bulk packed goods.

Materials Provided

  • Test cassette in single foil pouch with desiccant;
  • Disposable sample dropper;
  • Instruction leaflet.

To carry out the assay with a Anti-Syphilis S/WB/P Test Cassette, Serum, WB or Plasma should be collected according to the instructions given in the Instruction For Use included in the test kit. After collecting, it is preferable to perform the testing as early as possible; if not viable, the specimen should be stored properly. A general introduction about the collection, and storage of the specimens is given below.

Serum Collection

Collect blood specimen into a red top blood collection tube by vein puncture, which contains no anticoagulants.

Allow the blood to clot, or separate the serum by centrifugation.

Carefully withdraw the serum into a new pre-labeled tube.

Whole Blood Collection

Whole blood can be collected with blood collection tube with venipuncture into blood collection tube (containing EDTA, citrate or heparin).

Or, by lancet lancing. Clean the area to be lanced with an alcohol swab. Squeeze the end of the fingertip and pierce with a sterile lancet. Wipe away the first drop of blood with sterile gauze or cotton. Take a dropper provided, while gently squeezing the dropper tube, immerse the open end in the blood drop and then gently release the pressure to draw blood into the dropper.

Plasma Collection

Collect blood specimen into a lavender, blue or green top blood collection tube, containing EDTA, citrate or heparin, respectively, by vein puncture.

Separate the plasma by centrifugation.

Carefully withdraw the plasma into a new pre-labeled tube.

Serum, WB, Plasma Storage Condition

Test specimens as soon as possible after collecting.

The specimens can be stored up to 3 days at 2-8°C if not tested immediately. The specimens should be frozen at -20°C for longer time storage. Don’t freeze and thaw the specimens for many times.

Prior to testing, bring frozen specimens to room temperature slowly and mix gently.

Specimens containing visible particulate matter should be clarified by centrifugation before testing.

Do not use samples demonstrating gross lipemia, gross hemolysis or turbidity in order to avoid interference on result interpretation.

Colloidal Gold Chromatographic Immuno Double Antigen Sandwich method is used in this Anti-Syphilis S/WB/P Test Cassette to detect the Treponema Pallidum Antibodies in human Serum, WB or Plasma specifically. The introduction of this Colloidal Gold Chromatographic Immuno Double Antigen Sandwich testing principle is given blow.

GICA Double Antigen Sandwich Method Illustration

Double antigen sandwich technology is commonly used to detect total antibody, which include IgM, IgG and IgA antibodies, which all can react and bound to specific antigen. In the lateral flow double antigen sandwich chromatographic rapid test, recombinant or purified antigens are used to capture and detect the total antibodies specifically.

In the test band region, purified or recombinant antigens or proteins are immobilized. In the end of the membrane strip where the samples are supposed to be added, another antigen conjugated with colloidal gold particles is embedded.

During the testing process, specimen from the patient is added to the end of the membrane strip. The antigen conjugate particles resolve into the specimen, where the antigen conjugate will react and bound to the target antibodies, if present.

This antibody-antigen conjugate complex then moves along the strip to the testing band region, under capillary effect. Where the immobilized antigen captures the complex, and the antigen-antibody-antigen-colloidal gold complex is fixed on test band region. When the complex congregates, the highly concentrated colloidal gold particles will develop some red or pink color, indicate a positive result.

If there is no target antibody in the specimen, the colloidal gold particles will not congregate on the test band region, and no color will develop, indicating a negative result.
