Appearance Clear Glucose Trace Urobilinogen normal
Sp. Gravity 1.030 Ketones trace Nitrite negative
pH 5.0 Bilirubin negative Leukocyte negative

1.Explain the correlation between the patient’s blood and urine results. The renal threshold for glucose is exceeded.

2.What is the most probable metabolic disorder associated with this patient? Diabetes mellitus

Case Study 5
Results of a urinalysis on a patient scheduled for gall bladder surgery are: Color Amber Protein negative Blood negative
Appearance hazy Glucose negative Urobilinogen normal
Sp. Gravity 1.022 Ketones negative Nitrite negative
pH 6.0 Bilirubin moderate Leukocyte negative
1.What would be observed if this specimen was shaken?
Yellow foam in the urine

2.What confirmatory test should be performed on this specimen? Ictotest

3.How would this test differentiate between the presence of bilirubin and medication pigments? This tablet comes with a mat that allows substances other than bilirubin to seep through, in order for the tablet to test only for potential bilirubin. 4.Explain the difference between the patient’s scheduled surgery and the urinalysis results. A blockage in the bile duct would cause the bilirubin not to reach the intestine and thus be excreted by the kidneys, causing an abnormal bilirubin result, but normal urobilinogen result. 5.If blood were drawn from this patient, how might the appearance of...
