Testing Algorithm Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.
Initial testing includes: prothrombin time (PT), activated partial thromboplastin time (APTT), dilute Russells viper venom time (DRVVT), thrombin time (bovine), fibrinogen, D-dimer, soluble fibrin monomer, and special coagulation interpretation.
If PT is > or =14 seconds, PT mix will be performed.
If APTT is >36 seconds, APTT mix will be performed.
If APTT mix is >36 seconds with no evidence of heparin in samples, platelet neutralization procedure will be performed.
If DRVVT ratio is > or =1.2, DRVVT mix will be performed.
If DRVVT mix ratio is > or =1.2, DRVVT confirmation will be performed.
If thrombin time is >23 seconds, reptilase time will be performed.
If PT, APTT, or DRVVT is prolonged, coagulation factor assays may be performed.
