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

I’ll go with c, the renal biopsy. ASO is useful but not 100% sensi and only provides possible clue of association, not the diagnosis-the pathology
C is the answer
It seems a like presentation for PSGN so I would expect the RBCS ,hypertension,facial swelling and +anti-strep antibody but i expect a HX of URI -GI infection
I also do agree with NOOK seeing is believing !
C- Renal biopsy, no history of URI infection for causing post strep pathology prior to sympt onset.
biopsy

the problem here is ,that strep o,does not confirm the diagnosis of glomeruronephritis post strep,this title could be positive , if the pt ever in his life had contact with streptococcal,so the ans is ccccccccccccccc
renal biopsy is the best tool to confirm diagnosis….but aso titre is the best initial investigation……
i think is obvious and is B
