pH—6
protein—neg
glucose—½%
ketone—neg
bilirubin—neg
blood—neg
urobilinogen—0.1 EU
nitrite—neg
leukocyte esterase—neg
SG—1.020
a.   Identify abnormal results.
b.   What negative results are significant? Why?
c.   What follow-up or confirmatory tests are indicated?

Answer 1

URINALYSIS: The urinalysis is a non-invasive collection of urine specimen used to diagnose significant dignostic conditions.

NORMAL VALUES: The normal values for urinalysis are as follows: pH- 4.5-8, protein- 30mg/dL, glucose- 130mg/dL, ketone- negative, bilirubin-negative, blood-3RBCs, urobilinogen- 0.2-1.0mg/dL, nitrite- negative, leukocyte esterase- negative, specific gravity- 1.005-1.025

ABNORMAL RESULTS: The abnormal results of 52year old patient is glucose and protein due to diabetic mellitus. These levels are higher than the normal limits.

WHAT NEGATIVE RESULTS SINGNIFIES? Negative results signifies they are below or within the normal results.

WHAT FOLLOW-UP OR CONFIRMATORY TEST ARE INDICATED? Blood glucose test (fasting, postprandial and random blood sugar) is necessary to identify diabetes mellitus further as a confirmatory test.
