Definition - What does Partial Thromboplastin Time mean?
Partial thromboplastin time (PTT) is a blood test procedure that entails collecting a blood sample followed by chemical injections to analyze the coagulation process. Blood comprises platelets responsible for clotting at injury sites to inhibit excessive blood loss. A chemically-injected blood sample permits laboratory specialists to analyze the duration of clotting by comparing normal and abnormal PTT baseline standards.

Blood clotting serves as an ordinary biomechanical function that alerts the body to generate platelets to preserve blood volume against ruptured arteries and/or veins. A PTT examination is a practical method that can lend evidence to suspected blood diseases based on symptoms including easy bruising, heavy menstrual discharge, frequent nosebleeds and profuse bleeding from injuries (i.e. cuts). Auxiliary testing measures can bolster PTT test results suggesting blood clotting pathologies that include hemophilia, leukemia, Von Willebrand Disease, and vitamin K deficiency.
However, blood clotting also carries different etiological implications that can stem from health conditions such as obesity and heart disease. In addition, sedentary positions that require sitting for extensive periods of time can obstruct blood flow leading to the formation of deep vein thrombosis (DVT), typically developing in the leg or pelvis. A DVT that separates from its original location can travel through the bloodstream until it arrives at the lungs. Pulmonary symptoms can include coughing fits, chest pain, breathing difficulties leading to possible death.
A PTT test can be a viable method used to point to a possible blood disorder as the culprit for clotting issues. According to the Americans with Disabilities Act (ADA), a blood disorder is a legitimate disability because it disrupts normal circulatory system functions and processes. Individuals who confer with employers about a blood disorder are likely to avoid prejudice against a lack of personal communication supported by medical reports.
