Evaluation of Antiphospholipid Antibodies and Activated Partial Thromboplastin Time in Women with Adverse Outcome of Pregnancy
Adverse outcome of pregnancy is a potentially dangerous complication of conception and affects 15-20% of pregnancies. According to recent studies increased level of blood antiphospholipids antibodies, if accompanied by predisposing factors, can be an adverse event in human pregnancy. The aim of the present study was to compare the maternal serum levels of anticardiolipin and antiphosphatidyl se...
متن کاملA clinical evaluation of automated chromogenic tests as substitutes for conventional prothrombin time and activated partial thromboplastin time tests.
Automated procedures involving a chromogenic substrate sensitive to thrombin-sarcosine-Pro-Arg p-nitroanilide were compared with conventional tests for prothrombin times and activated partial thromboplastin times (APTT) and with specific assays for factors V, VII, VIII, IX, X, XI, and XII. The reproducibility and sensitivity of the chromogenic tests were compared with those of the clotting test...
متن کاملInfluence of sex on activated partial thromboplastin time (aPTT) and prothrombin time (PT) in sheep.
Haemostasis is a physiological process that prevents excessive blood loss. In laboratory, the prothrombin time (PT) and the activated partial thromboplastin time (aPTT) are used to examine clotting systems. However, the influence of sex on PT and aPTT values is unknown. The present work aimed to determine the values for PT and aPTT in adult sheep and to evaluate their dependence on the sex of t...
متن کاملEvaluation of Prothrombin Time and Activated Partial Thromboplastin Time in Hypertensive Patients Attending a Tertiary Hospital in Calabar, Nigeria
Introduction. Several biomedical findings have established the effects of hypertension on haemostasis and roles of blood coagulation products in the clinical course of hypertension. Methods. This cross-sectional study aimed at determining effects of hypertension on prothrombin time (PT) and activated partial thromboplastin time (APTT) in hypertensive patients in comparison with normotensive sub...
متن کاملStability of prothrombin time and activated partial thromboplastin time tests under different storage conditions.
Prothrombin time (PT) and activated partial thromboplastin time (aPTT) are common laboratory tests that are useful in the diagnosis of coagulation disorders and monitoring anticoagulant therapy. Recent expansions in the outreach laboratory services at our institution prompted us to investigate the shipping limitations for some tests, including PT and aPTT. Although we followed NCCLS guidelines ...
