Background and Purpose— Antiphospholipid antibodies have been associated with ischemic
stroke in some but not all studies. Methods— We performed a population-based case-…

Platelet aggregometry has been the reference method employed to detect, diagnose, and
monitor qualitative platelet disorders since the early 1960s. Lumiaggregometry and impedance…

Light transmittance aggregometry is the historical reference method for platelet function
testing and continues to be used extensively. Whole blood impedance lumiaggregometry …

Background The normalized dilute Russell viper venom time (DRVVT) ratio provides a robust
assay methodology for lupus anticoagulant (LA) detection. Objectives We evaluated six …

The purpose of this study was to determine whether the anti-activated factor X (anti-FXa)
assay is less affected by pre-analytical variables in monitoring patients on unfractionated …

The purpose of the present study was to compare the international normalized ratio with a
chromogenic factor X (CFX) assay for monitoring patients on oral anticoagulant therapy using …

BACKGROUND Diagnosis of Loxosceles reclusa envenomations is currently based upon
clinical presentation. An enzyme-linked immunosorbent assay (ELISA) can detect surface …

OBJECTIVE: A study was undertaken to determine the incidence of Acinetobacter baumannii
and methicillin resistant Staphylococcus aureus (MRSA) contamination on reusable …

The effect of repeated freeze–thaw cycles on anticardiolipin antibody levels was evaluated
using an enzyme-linked immunosorbent assay. Normal human serum was spiked with known …

The purpose of this study was to compare the ability of four commercial platelet function
assays to detect aspirin response in normal individuals taking 81 or 325 mg aspirin in a single-…
