Anti-coagulated fresh blood was distributed to the laboratories,and the results from the blood analyzers that day were compared with the reference values.

Study on quick innate immune adherent reaction of fresh blood corpuscle;

gonorrhoeae on dried fresh plasma gauze was laid aside for 24 h at 22℃, cultures of 20% of samples were positive, but no bacterial growth was observed after 48 h.

Objective To explore a practical way for traceability and comparability of the value obtained from clinical biochemical examination in regional medical organizations by transferring the assigned value in fresh serum to daily serum calibrator.

Objective To set up a calibration system for different hematology analyzers with fresh blood.

Methods Fresh blood assigned by hematology analyzer Sysmex XT-1800i as normative measurement system was used to calibrate two Sysmex KX-21 analyzers and one KX-21N analyzer respectively.

Objective To explore the application of fresh whole blood as the substitute calibrator on hematology analyzers.
