Annals of Clinical Biochemistry, Ahead of Print.
Case oneA young woman presented to the Early Pregnancy Assessment Unit (EPAU) with abdominal pain, amenorrhoea and variably positive home-pregnancy tests. On review, a point-of-care test (POCT) for urine beta-HCG (β-HCG) was negative but a blood test ...

Interpretable laboratory-data model for risk stratification of elevated NT-proBNP and its deployment in diagnostic support middleware

Annals of Clinical Biochemistry, Ahead of Print.
BackgroundHeart failure (HF) is a growing global burden. Although N-terminal pro–B-type natriuretic peptide (NT-proBNP) guides diagnosis, assay cost and analyzer availability limit routine use. Routine laboratory data may offer a low-cost triage ...

Falsely elevated urinary C-peptide during angiotensin receptor–neprilysin inhibitor therapy: A case report

Annals of Clinical Biochemistry, Ahead of Print.
BackgroundUrinary C-peptide testing is widely used to evaluate insulin secretion capacity from pancreatic β-cells. We report a case in which urinary C-peptide showed abnormally high levels during treatment with an angiotensin receptor–neprilysin ...

Paraprotein interference in bilirubin assays: A case of multiple myeloma highlighting the reliability of dry chemistry

Mon, 03/16/2026 - 06:41
Annals of Clinical Biochemistry, Ahead of Print.
The presence of paraproteins in multiple myeloma can cause analytical interference, resulting in unusual and misleading biochemical outcomes. An uncommon but clinically relevant finding is the reporting of a negative direct bilirubin result on wet ...
