What is a Partial thromboplastin time?
A test to check your blood clotting.
What are the precautions associated with the partial thromboplastin time test?
Precautions are that certain medications (antihistamines, vitamin C, aspirin and chlorpromazine) can affect the results of the PPT test.
How is the partial thromboplastin time test usually paid for?
The partial thrmoboplastin time test is usually covered by insurance.
How is the patient prepared for the partial thromboplastin time test?
The patient is asked what medications they are on, to see if they may influence test results. If the patient is on heparin therapy, the blood sample is drawn one hour before the next dose of heparin.
Medical term p.t.t. head?
PTT = Partial Thromboplastin Time (test). Don't know what and how 'head' relates to this.
Which drug effect does the partial thromboplastin time test monitor?
The PTT test can be used to monitor the effect of heparin on a patient's coagulation system.
What are abnormal results for a partial thromboplastin time test?
Abnormal results are increased levels in those with a bleeding disorder or liver disease. With those taking heparin, low levels indicate the dose is too low, high levels indicate the dose is too high.
What constitutes a normal PT test?
The normal prothrombin time is 11-15 seconds, although there is some variation depending on the source of the thromboplastin used in the test.
What are the risks associated with a partial thromboplastin time test?
Complications of a bruise or swelling around the puncture site, which can be treated with moist warm compresses. People with coagulation problems may bleed for a longer period than normal.
What is the use of adding activators to a partial thromboplastin time test?
The test can be done without activators, but they are usually added to shorten the clotting time, making the test more useful for monitoring heparin levels.
What is a coagulation cascade in a partial thromboplastin time test?
A coagulation cascade is the sequence of biochemical activities, involving clotting factors, that stop bleeding by forming a clot.
What color tube is used for a ptt test?
A light blue tube is typically used for a partial thromboplastin time (PTT) test. This tube contains sodium citrate as an anticoagulant to prevent blood clotting during the test.
