Test ID: AATHR    
Thrombophilia Profile, Plasma and Whole Blood

Useful For Suggests clinical disorders or settings where the test may be helpful

Evaluating patients with thrombosis or hypercoagulability states

 

Detecting a lupus-like anticoagulant; dysfibrinogenemia; disseminated intravascular coagulation/intravascular coagulation and fibrinolysis

 

Detecting a deficiency of antithrombin, protein C, or protein S

 

Detecting activated protein C resistance (and the factor V R506Q [Leiden] variant if indicated)

 

Detecting the prothrombin G20210A variant

Profile Information A profile is a group of laboratory tests that are ordered and performed together under a single Mayo Test ID. Profile information lists the test performed, inclusive of the test fee, when a profile is ordered and includes reporting names and individual availability.

Testing Algorithm Delineates situations 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 Russell viper venom time (DRVVT); thrombin time (bovine); fibrinogen; D-dimer; antithrombin activity; protein C activity; protein S antigen, free; prothrombin G20210A mutation; activated protein resistance V; and thrombophilia interpretation.

 

If PT is >13.9 seconds, PT mix will be performed at an additional charge.

 

If APTT is > or =38 seconds, APTT mix will be performed at an additional charge.

 

If APTT mix is > or =38 seconds and thrombin time is <35.0 seconds (no evidence of heparin), platelet neutralization procedure will be performed at an additional charge.

 

If DRVVT ratio is > or =1.20, DRVVT mix and DRVVT confirmation will be performed at an additional charge.

 

If thrombin time is > or =25.0 seconds, reptilase time will be performed at an additional charge.

 

If fibrinogen is <150 mg/dL, or clinically indicated, PT-Fibrinogen will be performed at an additional charge.

 

If D-dimer is >500 ng/mL FEU, soluble fibrin monomer will be performed at an additional charge.

 

If protein S antigen, free is <65% for males and females > or =50 years of age and <50% for females <50 years of age, protein S antigen, total will be performed at an additional charge.

 

If protein C activity is <70% with no evidence for an acquired decrease in protein C activity, protein C antigen may be performed at an additional charge.

 

If antithrombin activity is <80% with no evidence of an acquired decrease in antithrombin activity, antithrombin antigen will be performed at an additional charge.

 

If activated protein C resistance (APC) ratio is <2.3 or baseline APC APTT is prolonged, factor V Leiden (R506Q) variant analysis will be performed at an additional charge.

 

If appropriate, protein S activity, coagulation factor assays, or Staclot LA will be performed at an additional charge to clarify significant abnormalities in the screen test results.
