High Quality PT Tubes with CE &ISO
No Additive Tubes are widely used in blood collection and storage for biochemical, immunological, and serological tests in medical laboratories. These tubes ensure a sufficient and uncontaminated serum sample for clinical testing while maintaining the stability of the serum over long periods. They are compatible with all mainstream biochemical analyzers in the market, making them an essential tool in diagnostic procedures.

PT tubes are specifically designed for coagulation testing. They contain buffered trisodium citrate solution, available in two concentrations: 0.109 mol/L (3.2%) or 0.129 mol/L (3.8%), depending on the laboratory's requirements. The recommended mixing ratio is 1 part citrate to 9 parts blood, ensuring a precise blood-to-additive ratio. This feature guarantees accurate results for PT and APTT tests, providing optimal conditions for reliable coagulation analysis in clinical settings.
