SST Tiger Top is used for which types of tests?

• A. Coagulation tests
• B. DNA analysis
• C. Chemistry panels and serology tests
• D. Blood cultures

Answer: (C)

The main idea is that SST Tiger Top tubes are designed to produce clean serum for routine chemistry and serology testing. They contain a clot activator and a separator gel. After blood collection, the sample clots and is centrifuged, and the gel forms a barrier between the serum and the clot/cells. That serum is then used for many chemistry panels and serology assays because it provides a clear, cell-free matrix and doesn’t contain anticoagulants that could interfere with these tests. Coagulation tests, by contrast, require plasma with intact clotting factors, so they’re typically run on citrate-containing tubes that prevent clotting without removing factors—not on serum from an SST tube. For DNA analysis, serum is not ideal for many methods, which prefer whole blood or plasma collected in specific tubes (like EDTA) to preserve nucleic acids. Blood cultures need sterile collection into culture bottles without additives that could affect microbial growth, so an SST would not be appropriate there. So the SST Tiger Top is best suited for chemistry panels and serology tests because it yields serum suitable for those assays.
