| Popis: | Objectives To determine whether urine storage at room temperature for up to 2 h versus 4 h changes urinalysis results. Design and methods We compared the rejection rate at eight different hospital laboratories and concordance of urinalysis results (n = 83; two laboratories) between urines analyzed within 2 h and 4 h after collection. Results The rejection rate at the two hour cutoff was significantly higher as compared to the four hour cutoff. The concordance between urinalysis results was 97–100% between the two and four hour analyses. Conclusion Urine may be stored for up to 4 h at room temperature without significant changes to the urinalysis results. |
