Sample matrix and high-sensitivity cardiac troponin I assays

Background Manufacturers of high-sensitivity cardiac troponin (hs-cTn) assays have restricted use of what sample types or matrices are acceptable to use for measurement. Our goal was to evaluate the comparability of the Siemens ADVIA Centaur hs-cTnI assay across different matrices and under differen...

Our goal was to evaluate the comparability of the Siemens ADVIA Centaur hs-cTnI assay across different matrices and under different storage conditions. Methods Three different QC-plasma matrices were evaluated for imprecision &lt;10 ng/L. Passing-Bablok regression and difference plots were determined for cTnI concentrations spanning the reference interval (limit of quantification to male 99th-percentile: 2.5 ng/L to &lt;60 ng/L) between serum and lithium heparin plasma, lithium heparin and EDTA plasma and between the Siemens and Abbott hs-cTnI assays. Stability at room temperature (RT) and 2-8 °C was also assessed across the three matrices. Results Over 16-weeks the SDs were ≤1.0 ng/L for QCs ranging from 5.0 to 8.3 ng/L. Across the reference interval there was excellent agreement between lithium heparin plasma and serum for the Siemens hs-cTnI assay (slope=0.98/intercept=-0.1), however, cTnI concentrations were proportionally lower in EDTA as compared to lithium heparin plasma (slope=0.90, 95% CI: 0.88-0.92). In lithium heparin plasma the Siemens hs-cTnI concentrations were higher than the Abbott hs-cTnI concentrations (slope=1.26/intercept=-0.2). Stability of cTnI in lithium heparin plasma as compared in serum and EDTA plasma appeared more labile, with decreases ≥20% in concentrations evident as early as 1-day in storage at RT. Conclusions There is excellent agreement in concentrations between lithium heparin plasma and serum with the Siemens ADVIA Centaur hs-cTnI assay; however, cTnI concentrations in EDTA plasma are lower. Reference intervals and clinical studies in EDTA plasma for the Centaur hs-cTnI assay are required before clinical use.</description><identifier>ISSN: 1434-6621</identifier><identifier>EISSN: 1437-4331</identifier><identifier>DOI: 10.1515/cclm-2018-1100</identifier><identifier>PMID: 30838842</identifier><language>eng</language><publisher>Germany: De Gruyter</publisher><subject>analytical variation ; Anticoagulants ; Assaying ; Blood Chemical Analysis - standards ; Blood Specimen Collection ; Calcium-binding protein ; Edetic acid ; Edetic Acid - chemistry ; EDTA plasma ; Ethylenediaminetetraacetic acids ; Heart ; Heparin ; Heparin - chemistry ; high-sensitivity cardiac troponin ; Humans ; Immunoassay - standards ; Lithium ; lithium heparin plasma ; matrix ; Plasma ; Quality Control ; Reference Values ; Sensitivity ; serum ; Slope stability ; stability ; Stability analysis ; Storage ; Storage conditions ; Troponin ; Troponin I ; Troponin I - blood</subject><ispartof>Clinical chemistry and laboratory medicine, 2019-04, Vol.57 (5), p.745-751</ispartof><rights>2019 Walter de Gruyter GmbH, Berlin/Boston</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c376t-742a89a3b2897fccad1e426d0ea46ff628e59d293a3585768d2dc3be6055235c3</citedby><cites>FETCH-LOGICAL-c376t-742a89a3b2897fccad1e426d0ea46ff628e59d293a3585768d2dc3be6055235c3</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktopdf>$$Uhttps://www.degruyter.com/document/doi/10.1515/cclm-2018-1100/pdf$$EPDF$$P50$$Gwalterdegruyter$$H</linktopdf><linktohtml>$$Uhttps://www.degruyter.com/document/doi/10.1515/cclm-2018-1100/html$$EHTML$$P50$$Gwalterdegruyter$$H</linktohtml><link.rule.ids>314,776,780,27901,27902,66497,68281</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/30838842$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Kavsak, Peter A.</creatorcontrib><creatorcontrib>Roy, Chantele</creatorcontrib><creatorcontrib>Malinowski, Paul</creatorcontrib><creatorcontrib>Clark, Lorna</creatorcontrib><creatorcontrib>Lamers, Shana</creatorcontrib><creatorcontrib>Bamford, Karen</creatorcontrib><creatorcontrib>Hill, Stephen</creatorcontrib><creatorcontrib>Worster, Andrew</creatorcontrib><creatorcontrib>Jaffe, Allan S.</creatorcontrib><title>Sample matrix and high-sensitivity cardiac troponin I assays</title><title>Clinical chemistry and laboratory medicine</title><addtitle>Clin Chem Lab Med</addtitle><description>Background Manufacturers of high-sensitivity cardiac troponin (hs-cTn) assays have restricted use of what sample types or matrices are acceptable to use for measurement.
