Description
Jordi Tortosa-Carreres and co-authors sift in 2026 why two urine blood tests clash on the same sample in clinic analyzers. One test is a dipstick, the other a cell counter, and gaps between them can stall care. The team drew 3,399 urine samples from distinct primary care patients run on one analyzer family.
A ratio of small red cells to all red cells tied most strongly to the clash, with a second ratio for burst cells pulling the other way. Dirt in the sample and urine acidity also raised clash odds, while germ and white cell counts lowered them. The authors say the clash follows a set pattern that labs can flag in advance.
