Today, laboratories are very much different than
they were decades ago. They have improved
instruments to work with, multiple off-site collection
points, more competent personnel, a greater analyte
panel and quality requirements for those analytes.
Nevertheless, sample quality has to be assured along
the total testing process (TTP) in order to guarantee
reliable results to the patient. In routine coagulation,
prothrombin time (PT), activated partial thromboplastin
time (APTT), fibrinogen (Fbg) and D-dimer are
the essential part of the test panel, for which new
evidences about sample quality requirements have
been presented in recent years.
