Laboratory testing, a highly complex process commonly called the total testing process (TTP), is usually subdivided into three traditional (pre-, intra-, and post-) analytical phases. The majority of errors in TTP originate in the pre-analytical phase, being due to individual or system design defects. In order to reduce errors in TTP, the pre-analytical phase should therefore be prioritized. In...
Intraplatelet phospho-VASP analysis is a commonly used approach for monitoring of anti-platelet therapy; however, testing of intraplatelet phospho-VASP expression needs a high level of experience and proficiency. The ability to recognize how the pre-analytical variations can change the results would be helpful for the interpretation of data from intraplatelet P-VASP analysis. The aim of this st...
BACKGROUND Most prior studies of racial differences in the delivery of cardiac care have focused on potential differences in treatment by individual physicians and hospitals. However, differential use of hospitals with variable practice patterns might also contribute to variations in care. METHODS AND RESULTS We compared the use of bioprosthetic valves (BPVs) in 78,154 black and white Medicar...
BACKGROUND Individual participant data (IPD) meta-analyses that obtain "raw" data from studies rather than summary data typically adopt a "two-stage" approach to analysis whereby IPD within trials generate summary measures, which are combined using standard meta-analytical methods. Recently, a range of "one-stage" approaches which combine all individual participant data in a single meta-analysi...
Monitoring of Turnaround time (TAT) in Biochemistry Laboratory of a tertiary care hospital in Punjab
Turnaround time (TAT) is commonly defined as the time from when a test is ordered until the result is reported which includes the preanalytical, analytical and post-analytical time. Increased attention to patient’s needs is demonstrated by efforts to improve the quality of the entire service provided, e. g reduction of laboratory turnaround time (TAT). The availability of the results from a lab...
