Summary: Bilirubin, first detected in blood in 1847, is widely used as a biomarker for liver disease. However, the current gold standard colorimetric test for bilirubin has limitations and lacks a bedside option, leading to delays in clinical decisions. To bridge this care gap, bioengineered point-of-care bilirubin assays are being developed. This Perspective critically discusses these recently developed assays and evaluates their potential for translation.

Summary: This study investigated the utility of a finger prick method for full blood counts (FBC) in clozapine patients. The results showed that the point of care testing (POCT) finger prick method provided comparable results to the standard laboratory venous method. The availability of an accurate capillary monitoring method may improve clozapine uptake and adherence.

Summary: Large parallel data sets, collected from multiple sources over time, consist of paired measurements of responses and covariates. A residual-aggregated testing (RAT) method is proposed to identify the data sources where the regression relationship of each data set has shifted. The proposed method incorporates the dependence structure among different data sets and is more robust than the conventional Benjamini-Hochberg method. Under mild conditions, the asymptotic validity for false discovery proportion and FDR control is established. Extensive numerical results confirm the effectiveness and robustness of the proposed method.

Summary: Although point of care testing (POCT) for infectious diseases is commonly available in all EU/EEA countries, its potential to support public health functions such as disease surveillance and reporting is underutilized. While POCT has the potential to improve clinical care by providing faster diagnoses and more appropriate use of antimicrobials, further research is needed to fully realize its benefits in wider public health functions.
