Blood thinners will make blood take longer to clot so a patient taking a blood thinner would be expected to have lab results that are higher longer than the ones listed here. Doctors call this prolonged ptt.

Addressing Clinical Etiologies Of A Prolonged Aptt

This means that it took your blood sample 25 to 35 seconds to clot after adding the chemicals.

Ptt blood test normal range. A number lower than that range means blood clots more quickly than normal. A number higher than that range means it takes blood longer than usual to clot. The reference range of the aptt is 30 40 seconds.

1 2 3 the. 30 to 45 seconds this can value slightly from lab to lab inr. The average time range for blood to clot is about 10 to 13 seconds.

Your lab report should contain the range your lab uses. Partial thromboplastin time ptt is a blood test that measures the time it takes your blood to clot. The aptt is considered a more sensitive version of the ptt and is used to monitor the patient s response to heparin therapy.

Ptt test results are measured in seconds. The activated partial thromboplastin time normal range is between 30 to 40 seconds while the partial thromboplastin time normal range is between 60 to 70 seconds. These ranges vary from lab to lab and your lab may have a different range for what s normal.

Prothrombin time test results can be presented in two ways. If you re getting the test to monitor heparin your normal will be higher usually between 60 and 100 seconds. If your results are above the normal range your blood clots more slowly.

This ratio which allows for easier comparisons of test results from different laboratories is used if you take blood thinning medications. Making sense of blood thinners for surgery patients. Normal results are typically 25 to 35 seconds.

The normal values listed here called a reference range are just a guide. But generally clotting time is fine if it s within 25 to 35 seconds.
