Age-dependent discordance in chemiluminescent immunoassay-electrochemiluminescence immunoassay correlation for 25-hydroxyvitamin D measurement reveals methodological considerations for assessment in early infancy [PDF]

Endocrine Journal
Vitamin D (VD) status is assessed by measuring serum 25-hydroxyvitamin D (25(OH)D) levels using immunoassays. In December 2024, a Japanese diagnostic laboratory transitioned from chemiluminescent immunoassay (CLIA: LIAISON® 25 OH Vitamin D Total Assay ...

Anti-thyroid peroxidase (TPO) antibodies – Comparative analysis of two automatic methods, ECLIA and CMIA

Romanian Journal of Laboratory Medicine
Introduction: Anti-thyroid peroxidase autoantibodies (TPO) is an essential diagnostic tool for autoimmune disorders of the thyroid gland. However, TPO results are not always comparable due to differences between methods. Here, we aimed to investigate the

Analytical performance evaluation of the Elecsys® Cyclosporine and Elecsys® Tacrolimus assays on the cobas e411 analyzer

Practical Laboratory Medicine, 2017
Background: Cyclosporine (CsA) and tacrolimus (TAC) are immunosuppressant drugs that are often used to treat autoimmune diseases and as transplantation therapy; therefore, their concentrations need to be monitored carefully.

The measurement of immunosuppressive drugs by mass spectrometry and immunoassay in a South African transplant setting

Practical Laboratory Medicine
Objectives: Liquid chromatography tandem mass spectrometry (LC-MS/MS) is the gold standard for measurement of immunosuppressive drugs (ISDs), but is technically demanding and less accessible in resource-limited countries.

Interference of hemolysis on the postmortem biochemical analysis of IgE by ECLIA [PDF]

International Journal of Legal Medicine, 2021
Forensic diagnosis of anaphylactic shock is a challenging task in forensic practice due to the lack of characteristic morphological changes. Postmortem analysis of serum IgE can provide helpful information for determining anaphylaxis. However, postmortem serum always suffers from hemolysis.
