Glial fibrillary acidic protein (GFAP) and ubiquitin carboxyl-terminal hydrolase L1 (UCH-L1) may aid in the evaluation of traumatic brain injury (TBI). The objective this analysis was to compare GFAP UCH-L1 values measured using a handheld device compared with core laboratory platform. We analyzed plasma samples from patients TBI healthy controls enrolled Transforming Research Clinical Knowledg...
Abstract Background Thyroid function tests (TFT) which usually include thyroid stimulating hormone (TSH), total triiodothyronine (TT3), and free thyroxine (FT4) are widely applied in clinical practice for screening, diagnosis monitoring of disease. We evaluated analytical performance TSH, TT3, FT4 using DxI800 (Beckman Coulter, USA) including comparison to Alinity I (Abbott, USA). Methods Preci...
Analyzing values of two different machines for the same parameter allocates clinician’s discretion for medical decisions and important tool for method validation. Electrolyte samples of 635 patients were measured using ABG and Dry chemistry analyzer. The Mean for Sodium by Dry chemistry analyzer was 134.6 (±7. 59) and by ABG analyzer 134.1 (±7. 57), that of Potassium 3.7 (±0. 7) and 3.5 (±0. 67...
1. Guidelines for thromboplastins and plasmas used to control anticoagulant therapy. World Health Organization Committee on Biological Standardization. WHO Technical Report Series 1999; 889:64-93. 2. van den Besselaar AM, Breddin K, Lutze G, Parker-Williams J, Taborski U, Vogel G, et al. Multicenter evaluation of a new capillary blood prothrombin time monitoring system. Blood Coagul Fibrinolysi...
INTRODUCTION Lipoprotein-associated phospholipase A2 (Lp-PLA2) is a marker of vascular inflammation associated with coronary heart disease and stroke. We evaluated analytical performance of the PLAC® Activity Test on Siemens Dimension Vista® 1500 analyzer and measured Lp-PLA2 activity in Italian adults to establish reference intervals (RIs) and evaluate correlation with circulating lipids and a...
BACKGROUND The comparability of total and free prostate-specific antigen (tPSA and fPSA) results among commercial PSA assays has been suggested to be improved by calibration to WHO PSA reference materials and the development of equimolar-response assays. To characterize the current situation, we assessed 5 frequently used commercial assay combinations for tPSA and fPSA regarding the interchange...
BACKGROUND Because mycophenolic acid (MPA) is highly protein bound and because the free fraction is the pharmacologically active portion, a rapid, reliable, and sensitive procedure is required to study the relationship between free MPA and treatment efficacy/toxicity. Liquid chromatography-tandem mass spectrometry is ideally suited for such a method. METHODS Free MPA was isolated from plasma ...
A high prevalence of genetic polymorphisms increases sensitivity to warfarin therapy. In this study, we investigated 47 patients with effective long-term therapy by warfarin well-controlled by monitoring of International Normalised Ratio (INR). All patients were tested for gene polymorphisms VKORC1, CYP2C9*C2, and CYP2C9*C3, which were used for a dose calculation employing a program www.Warfari...
BACKGROUND The cerebrospinal fluid (CSF) amyloid-β (Aβ42) peptide is an important biomarker for Alzheimer's disease (AD). Variability in measured Aβ42 concentrations at different laboratories may be overcome by standardization and establishing traceability to a reference system. Candidate certified reference materials (CRMs) are validated herein for this purpose. METHODS Commutability of 16 c...
Data regarding the quantification of CD34+ hematopoietic stem cell HSC in dual-platform (DP) approach using a hematological analyzer featuring dedicated nRBC channel are limited if not inexistent. The objective this study is to compare performance DP on new generation channel, Sysmex XN-1000, with single-plate (SP) form Beckman Coulter’s Navios flow cytometer. Using International Society for He...
