Normal results vary based on the method and activators used. Normal APTT results are usually between 25-40 seconds; PTT results are between 60-70 seconds.APTT results for a patient on heparin should be 1.5-2.5 times normal values.An APTT longer than 100 seconds indicates spontaneous bleeding.artial thromboplastin time (PTT), a test for detecting coagulation defects of the intrinsic system by adding activated partial thromboplastin to a sample of test plasma and to a control sample of normal plasma. The time required for the formation of a clot in test plasma is compared with that in the normal plasma.
This enzyme is also called alanine transaminase, or ALT. The normal GPT usually range for adults in most labs is 0 to 35 units per liter (U/L). The normal range may vary slightly from lab to lab.Your SGPT level may be much higher than normal (up to 50 times the upper limit of normal) if: * You have liver damage from an acute viral infection such as viral hepatitis A, B, or C. * You have liver damage caused by medicines you have taken.he normal range may vary slightly from lab to lab.
