In 1871, Mendeleev published his periodic table in a new form, with groups of similar elements arranged in columns rather than in rows, and those columns numbered I to VIII corresponding with the element's oxidation state.
the normal range for WBC in urine is 0 - 5/HPF. Mine was 40 - 50. The best thing to do is to discuss these results with your primary care doctor. White blood cells (WBC) in urine is usually measured in something called a urine analysis (UA) The normal range is 0-5 wbc/hpf, like you mentioned. This test is usually ordered to determine is someone has a urinary tract infection. Often patients will complain of dysuria (pain on urination) or urinary urgency.
False positive results may occur when patients are on large doses of chloropromazine, and may occur in the presence of metabolites of phenazopyridine. When these compounds are present, the urine becomes red. Metabolites of etodolac may cause false-positive or atypical results. False-negative bilirubin reagent strip results are often due to testing a specimen that is not fresh. Bilirubin breaks down when exposed to light.
