FAQ
What is a clot activator tube used for?
Collecting blood that requires serum. The activator promotes clotting before serum separation, used in biochemical, serological, and immunological analyses.
Clot tube vs. EDTA tube?
A clot tube is for serum; an EDTA tube is for whole-blood and hematology testing. The test determines the choice.
Serum vs. plasma?
Serum is the liquid left after blood clots (collected in these blood specimen tubes); plasma comes from un-clotted blood and still contains clotting factors.
Which tests use serum tubes?
These blood sample collection tubes are used for biochemistry, LFT, KFT, lipid profiles, hormone testing, serology, and immunology.
How long before serum separation?
Clotting time varies by protocol — follow your lab's established procedure before centrifugation.
Are they single-use?
Yes — these blood sample collection tubes are single-use; dispose of each per biohazard procedures after use and never reuse.
Suitable for NABL-accredited labs?
Suitable for routine collection and serum prep; labs should evaluate against their own quality and accreditation requirements.
