Default Pediateric Question

A 7-year-old boy is brought to the emergency department by his mother because of “tea-colored urine” for the last several days. He has also had some nausea and vomiting, and his eyes appear swollen when he wakes up in the morning. The eye swelling tends to resolve over the course of the day. He is generally very healthy and there is no family history of any chronic diseases. His temperature is 36.7 C (98.0 F), blood pressure is 130/90 mm Hg, pulse is 96/min, and respiratory rate is 16/min. Physical examination is unremarkable. A urinalysis shows red cell casts. At this time the most appropriate study to confirm your diagnosis is

A. antinuclear antibody
B. antistreptolysin O antibody
C. renal biopsy
D. renal ultrasound
E. urine culture

ok C is not done in this case...Renal ultrasound wont confirm anything and urine culture is out of the question too...ana is too no specific....antistreptolysin would need a previous history of GAS infection...if anything i would go with B.

B, child with hematuria the most common cause based on the options given is PSGN, even if no previous history of streptococcal infection was given, you need to document it with either ASO or antiDNAse B antibody.
You dont do renal biopsy unless is refractory or the disease progresses to RPGN with crescents.
