A simple equation to correct for gadolinium interference on plasma selenium measurement using inductively coupled plasma mass spectrometry.

Ann Clin Biochem 2020 May 3;57(3):234-241. Epub 2020 May 3.

Sullivan Nicolaides Pathology, Brisbane, Australia.

Background: The measurement of selenium in human plasma is useful to assess deficiency or toxicity. The presence of gadolinium in clinical samples following administration of certain contrast agents used for magnetic resonance imaging can cause a significant positive bias in selenium results when measured using quadrupole inductively coupled plasma mass spectrometry (Q-ICP-MS).

Methods: A mathematical equation to correct for gadolinium interference was assessed using both patient samples and commercial quality control/external quality assurance (QC/EQA) materials spiked with gadolinium. Read More

Electrolyte imbalances in patients with severe coronavirus disease 2019 (COVID-19).

Ann Clin Biochem 2020 05 3;57(3):262-265. Epub 2020 May 3.

Cardiac Intensive Care Unit, The Heart Institute, Cincinnati Children's Hospital Medical Center, Ohio, USA.

Background: Early studies have reported various electrolyte abnormalities at admission in patients who progress to the severe form of coronavirus disease 2019 (COVID-19). As electrolyte imbalance may not only impact patient care, but provide insight into the pathophysiology of COVID-19, we aimed to analyse all early data reported on electrolytes in COVID-19 patients with and without severe form.

Methods: An electronic search of Medline (PubMed interface), Scopus and Web of Science was performed for articles comparing electrolytes (sodium, potassium, chloride and calcium) between COVID-19 patients with and without severe disease. Read More

A method for measuring glycerol-blanked triglyceride concentrations by using gas chromatography-isotope dilution mass spectrometry.

Ann Clin Biochem 2020 May 27;57(3):253-261. Epub 2020 Apr 27.

Public Health, Department of Social Medicine, Graduate School of Medicine, Osaka University, Osaka, Japan.

Background: Serum triglyceride concentrations are measured as total glycerides content in many Western countries. In Japan, glycerol-blanked triglycerides (TG-GB) are measured to identify postprandial hypertriglyceridaemia and to minimize the influence of glycerol formulation on serum triglyceride values. However, TG-GB measurements have not been standardized. Read More

Plasma viscosity: Evaluation of a new measuring method using microfluidic chip technology (microVisc™) for clinical use and determination of a new reference range.

Ann Clin Biochem 2020 May 27;57(3):249-252. Epub 2020 Apr 27.

Department of Clinical Biochemistry and Pharmacology, Odense University Hospital, Odense, Denmark.

Background: Plasma viscosity is an important biomarker both in diagnostics and treatment monitoring of plasma cell dyscrasias and other disorders with hyperviscosity syndrome as a clinical manifestation. Here, we investigate the performance of a new microfluidic-based viscometer for clinical use, establish a new reference range to be used with this instrument and determine the importance of sampling temperature.

Methods: The microVisc™ viscometer was evaluated for within-run and between-run imprecision and bias using standardized reference material (Paragon controls) and Seronorm™ control material. Read More

Evaluation of 24-h urine containers for urine copper measurement by inductively coupled plasma mass spectrometry.

Ann Clin Biochem 2020 May 6;57(3):246-248. Epub 2020 Apr 6.

Clinical Biochemistry, Manchester University Hospitals NHS Foundation Trust, Manchester, UK.

Objective: To determine the necessity for acid-washed containers for 24-h urine copper analysis.

Methods: Copper solutions, with concentrations relevant to clinical decision limits, were prepared by spiking both assay diluent and unknown urine samples with the copper calibrator. Samples were split between plain and acid-washed 24-h urine containers, and copper analysis was performed using inductively coupled mass spectrometry (ICP-MS). Read More

Screening for thyroid disease in patients with type 2 diabetes mellitus: An evaluation of current practice.

Ann Clin Biochem 2020 May 25;57(3):242-245. Epub 2020 Mar 25.

Department of Clinical Biochemistry, University Hospitals of North Midlands NHS Trust, Stoke-on-Trent, UK.

Background: United Kingdom national guidelines do not recommend routine testing for thyroid disease in people with type 2 diabetes mellitus (T2DM). However, some studies suggest an increased risk of thyroid dysfunction in T2DM. The aim of this study was to evaluate the current practice of screening for thyroid disease in patients with T2DM.

Verification of placental growth factor and soluble-fms-like tyrosine kinase 1 assay performance in late pregnancy and their diagnostic test accuracy in women with reduced fetal movement.

Ann Clin Biochem 2020 May 25;57(3):223-233. Epub 2020 Mar 25.

Maternal and Fetal Health Research Centre, University of Manchester, Manchester, UK.

Background: Placental growth factor (PlGF) and soluble-fms-like tyrosine kinase 1 (sFlt-1) are biomarkers of placental function used to aid the diagnosis and prediction of pregnancy complications. This work verified the analytical performance of both biomarkers and provides preliminary diagnostic accuracy data to identify adverse pregnancy outcome in women with reduced fetal movement.

Methods: Verification of sFlt-1 and PlGF assays included a comparative accuracy assessment of 24 serum samples analysed at six different sites and laboratory-specific precision estimates. Read More

Chemical Pathology, Royal Melbourne Hospital, Melbourne, VIC, Australia.

Background: Patient-based real-time quality control (PBRTQC) techniques have been described in clinical chemistry for over 50 years. PBRTQC has a number of advantages over traditional quality control including commutability, cost and the opportunity for real-time monitoring. However, there are few systematic investigations assessing how different PBRTQC techniques perform head-to-head. Read More
