Am Fam Physician. 2005 Dec 1;72(11):2182.

The article “Diagnosis and Management of Acute Pyelonephritis in Adults,” (March 1, 2005, page 933) contained an error in Table 3, which discussed the laboratory diagnosis of urinary tract infection. In this table, the sensitivity and specificity for nitrate test were inadvertently transposed, and should have been listed as 35 to 85 percent sensitivity and 92 to 100 percent specificity. The online version of this article has been corrected, and the corrected Table 3 is reprinted below.

TABLE 3
Laboratory Diagnosis of Urinary Tract Infection

Test	Finding	Sensitivity (%)*	Specificity (%)*
Urinalysis16,17	> 5 WBCs/HPF	72 to 95	48 to 82
	> 10 WBCs/HPF	58 to 82	65 to 86
Leukocyte esterase test3	Positive	74 to 96	94 to 98
Nitrite test18	Positive	35 to 85	92 to 100
Leukocyte esterase and nitrite tests15,19	Either test positive	75 to 84	82 to 98
Dipstick hematuria20	Positive	44	88
Gram stain of uncentrifuged urine21	> 1 bacterium per HPF	93	95

WBCs/HPF = white blood cells per high-power field.

*—For identification of > 100,000 colony-forming units per mm3.
