Patient posture for blood collection by venipuncture: recall for standardization after 28 years

BACKGROUND Although data about the effect of posture on routine hematological testing were published 28 years ago, this pre-analytical issue has not been standardized so far. This study was planned to evaluate whether postural changes influence the results of hematology testing. METHODS A complete blood count was performed in 19 healthy volunteers after 25min in the supine position, 20min in ...

Collection of blood specimens by venipuncture for plasma-based coagulation assays: necessity of a discard tube.

The Clinical and Laboratory Standards Institute (CLSI) recently abandoned its recommendation for drawing a discard tube when performing a prothrombin time (PT)/international normalized ratio (INR) or an activated partial thromboplastin time (APTT). Because there is currently no evidence that a discard tube is necessary for more specialized coagulation assays, we studied the need for a discard t...

Optimizing pediatric venipuncture: ensuring successful blood sample collection with minimal stress and pain

Background The Canadian Healthy Infant Longitudinal Development (CHILD) study is a multicenter prospective birth cohort study designed to examine genetic and environmental factors related to the development of childhood asthma, allergies, and atopic dermatitis. The CHILD study events include the collection of blood samples at ages 1 and 5 years for all subjects. Blood collection is a critical a...

Standardizing data collection in traumatic brain injury.

Collaboration among investigators, centers, countries, and disciplines is essential to advancing the care for traumatic brain injury (TBI). It is thus important that we "speak the same language." Great variability, however, exists in data collection and coding of variables in TBI studies, confounding comparisons between and analysis across different studies. Randomized controlled trials can nev...
