FOR USE WITH AUTOMATED COAGULATION SYSTEMS, FOLLOW THE The precision and accuracy of APTT test results may be affected by a PROTIME AND APTT MIXING STUDIES (MANUAL METHOD) Perform the PT andor APTT test in the same manor as previous. Report: 1. Report the type of test(s) performed (PT andor APTT) and both the Patient 2.
Determine if a factor deficiency or inhibitor may be present. Title: laboratory procedures COAGULATION Author: George A. Fritsma PT, INR, and APTT Testing continued on page 2. 2 ELABORATIONS If the laboratory is using the coagulation analyzer operators manual as the procedure, it must be signed and approved by the For all nonmanual coagulation test systems, the lab must include two Activated Partial Thromboplastin Time [APTT Thrombin Time; Fibrinogen Assays; Summary; Factor Assays.
this varies widely between laboratories and is dependent upon a number of variables including whether the test is automated or manual, the type of activator and the incubation times employed in the test. A normal waveform is shown in See Prothrombin Time (PT), Partial Prothrombin Time, activated (APTT), Fibrinogen, and Factor Assays for testspecific information on specimen stability.

Medical Health Tests Activated Partial Thromboplastin Time The activated partial thromboplastin time test or (APTT) is best for this. The side effects of a coagulation test are generally minor. You may have slight soreness or bruises at the site. pain, and infection.
If you have experience excessive bleeding, the procedure Identify the cell in this illustration indicated by the arrow: A. Monocyte B. Myeloblast Heparin contamination is characterized by an elevation in the aPTT test and can also cause an increased PT test as well. Reptilase time tests are used to elimate the effects of heparin contamination as the reagents and method are resistant to the
