Abstract

BACKGROUND
Most of the blood-test samples are collected and carried in vacuum tubes. We have compared a newly developed vacuum tube, ‘Vacuon’ (Medion, Korea) and ‘BD Vacutainer®’ (BD, USA) in three common clinical assays, i.e., hematological, chemical, and immunological tests.
METHODS
A sum of 60 healthy volunteers were recruited in our study and their peripheral blood samples were collected in the tubes of the two brands. EDTA-tube samples were evaluated using 25 hematological tests. Serum separating tube samples were analyzed for 24 chemical parameters and the 3 thyroid hormones. The results were statistically analyzed using the paired t-test and Bland-Altman plot. In addition, the assay outcomes at t=0 hr were compared with those at t=24±2 hr for each of the tubes.
RESULTS
The assay results of 22 hematological parameters, 24 chemical parameters, and 3 thyroid hormones had a statistically significant correlation between the 2 brands of vacuum tubes (t=0 hr). Two hematological parameters (mean corpuscular hemoglobin concentration [MCHC] and cell hemoglobin concentration mean [CHCM]) showed higher mean values, while a hematological parameter (lobularity index [LI]) showed lower mean values in Vacuon than BD Vacutainer (t=0 hr). The results after 24 hr showed similarity between the 2 brands, with some inconsistent results in BD Vacutainer (Mean platelet volume [MPV], plateletcrit [Pct], eosinophil, calcium, and triiodothyronine) and Vacuon (MPV, hemoglobin distribution width [HDW], CHCM, Pct, eosinophil, and calcium).
CONCLUSIONS
BD Vacutainer and Vacuon tube showed good statistical concordance rate with some exceptions in the hematological parameters (MCHC, CHCM, and LI).
