Week 1 Urinalysis Case Study
CLS460 Clinical Practicum
Urinalysis Case Study
Part I:
A 14-year-old boy who has recently recovered from a sore throat develops edema and hematuria.
Significant laboratory results include a BUN of 30 mg/dL (normal 8–23 mg/dL) and a positive
Streptozyme test result. Results of a urinalysis are as follows:
COLOR: Red KETONES: Negative
CLARITY: Cloudy BLOOD: Large
SP. GRAVITY: 1.020 BILIRUBIN: Negative
PH: 5.0 UROBILINOGEN: Normal
PROTEIN: 3+ NITRITE: Negative
GLUCOSE: Negative LEUKOCYTE: Trace
Microscopic:
100 RBCs/hpf—many dysmorphic forms
5–8 WBCs/hpf
0–2 granular casts/lpf
0–1 RBC casts/lpf
1. What disorder do these results and history indicate?
2. What specific organism and virulence factor was responsible for the patient’s sore
throat?
3. What is occurring within this disease that leads to large amounts of blood in the
urine?
4. If the above urinalysis results were seen in a 5-year-old boy who has developed a
red, patchy rash following recovery from a sore throat, what disorder would be suspected?
1. Is the urine pH consistent with the appearance of uric acid crystals?
2. Is there any correlation between the urinalysis results and the substance observed in
the child’s diapers?
3. What disorder do the patient’s history and the urinalysis results indicate?
4. What enzyme is missing in this disease?
1. What specific disease do the patient’s laboratory results and history suggest along
with the end-stage renal disease that is occurring?
2. What is the significance of the positive result for urine glucose?
