The two alternative methods displayed the same rate of sensitivity 92(range: 81 - 100). Specificity rates reported were 62 (range: 56 - 69) for dipstick only and 49(range: 42 - 55) for combined dipstick and microscopic urinalyses. Positive and negative predictive values per test were, 22(range: 14 - 30), 99(range: 96 - 100) for dipstick only and 17(range: 10 - 23),and 98(range: 95 - 100) for combined test, respectively.
