-improper technique of collecting sample.

-Certain drug intake

-High specific gravity is seen in intake of some antibiotics, such as tetracycline.

-large amounts of glucose or ascorbic acid can cause false negative leukocyte esterase results.

-Urinalysis testing should be conducted on unspun urine.

-Refrigerated specimens should come to room temperature before analysis because many of the enzymatic reactions on the reagent strips are temperature dependent.

-Reagent strips must be handled properly which can cause false reports.
