Carryover Effects in Sibling Comparison Designs

Epidemiology, 2016
A convenient way of dealing with confounding is the sibling comparison design, where the outcome in exposed individuals is compared with the outcome in their unexposed siblings. The standard analysis of sibling comparison designs assumes that the exposure and outcome of an individual do not affect the exposure and outcome of his/her siblings, sometimes

Relevance of EDTA carryover during blood collection

Clinical Chemistry and Laboratory Medicine (CCLM), 2015
AbstractThe order of draw is regarded as a preanalytical issue to prevent carryover of additives during blood collection. Our objective was to prove the theory of ethylenediaminetetraacetic acid (EDTA) carryover for a closed vacuum system and the influence of EDTA on concentrations of selected biomarkers.To test the carryover of EDTA, a blood ...
