MeSH. D010314. [ edit on Wikidata] The partial thromboplastin time ( PTT ), also known as the activated partial thromboplastin time ( aPTT or APTT ), is a blood test that characterizes coagulation of the blood. A historical name for this measure is the kaolin-cephalin clotting time ( KCCT ), [ 1] reflecting kaolin and cephalin as materials ...
Adult male PT normal range is 9.6–11.8 seconds, while adult females' normal range is 9.5–11.3 seconds. [6] Internationalized normalized ratio (INR) is also a warfarin study, with therapeutic ranges of 2–3 for standard warfarin and 3–4.5 for high-dose warfarin. [6]
The aPTT-based APC resistance test involves a modified aPTT test performed in the presence and absence of activated protein C (APC). [1] [5] The ratio of these aPTT values is calculated and is called the APC sensitivity ratio (APCsr) or simply APC ratio (APCr). [1] [5] This ratio is inversely related to the degree of APC resistance. [7]
003436. [ edit on Wikidata] Liver function tests ( LFTs or LFs ), also referred to as a hepatic panel, are groups of blood tests that provide information about the state of a patient's liver. [ 1] These tests include prothrombin time (PT/INR), activated partial thromboplastin time (aPTT), albumin, bilirubin (direct and indirect), and others.
The thrombin time ( TT ), also known as the thrombin clotting time ( TCT ), is a blood test that measures the time it takes for a clot to form in the plasma of a blood sample containing anticoagulant, after an excess of thrombin has been added. [ 1] It is used to diagnose blood coagulation disorders and to assess the effectiveness of ...
t. e. Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry ...
Testosterone is measured in nanograms per deciliter (ng/dL). At its peak, during your adolescent years, a normal range for your testosterone is anywhere between 300 and 1,200 ng/dL. When you're ...
003656. [ edit on Wikidata] Bleeding time is a medical test done on someone to assess their platelets function. It involves making a patient bleed, then timing how long it takes for them to stop bleeding using a stopwatch or other suitable devices. The term template bleeding time is used when the test is performed to standardized parameters.
