Methods: This study utilized expired UltraTag RBC kits with luminescent paint, which stood in place for blood (n= 6). Each kit was prepared individually, and the preparation area (the chuck) was visually assessed for blood contamination with a black light in a dark room. A one sample t-test was used to assess the mean of population and whether it is significantly different from a hypothesized value of zero. Results: Three of the chucks used to prepare individual UltraTag RBC kits had contamination spots, while three had no contamination. Conclusions: It was not confirmed that a separate space should be used when preparing an UltraTag RBC kit.
