Not all sugars are equal: galactose interference leading to false hyperglycaemia in a case of classical galactosaemia
Manoy et al.
The finding, in our words
A female infant with classical galactosaemia showed falsely elevated glucose readings on a point-of-care glucometer due to high galactose levels, which are known to interfere with certain glucose measurement methods. This discrepancy can serve as a clinical clue for diagnosing galactosaemia and underscores the importance of reference laboratory confirmation in newborns with metabolic symptoms.

Frequent dried blood spot sampling detected early changes in beta-cell function more effectively than mixed-meal tolerance tests or urine ratios, supporting its potential as a decentralised monitoring tool for clinical trials.

Fingerstick capillary sampling showed strong agreement with venous sampling for mycophenolic acid, tacrolimus and cyclosporine A, with acceptable bias and improved agreement for mycophenolic acid after haematocrit correction. This minimally invasive approach may reduce procedural burden and support outpatient or home based therapeutic drug monitoring in children.
This study validated a method requiring only 10 microlitres of serum and found high agreement between fingerstick capillary samples and venous serum for monitoring twelve antibiotics. The results suggest capillary serum sampling is a feasible, minimally invasive alternative that avoids the haematocrit effect associated with whole blood microsampling.
The study developed and validated a rapid LC-MS/MS method for quantifying cefazolin in capillary whole blood collected via VAMS, plasma, and plasma ultrafiltrate, showing robust performance across matrices and successful application in a pediatric pilot cohort for therapeutic drug monitoring.

Neonatal capillary blood sampling procedures are reported inconsistently, with pain and sample quality as primary outcomes. Inconsistent reporting of decontamination, supportive care, and device use impedes best-practice development and should be prioritised in future research to support decentralised diagnostics.
