الإجابة: D. Urine albumin to creatinine ration test
The urine albumin-to-creatinine ratio detects moderately increased albuminuria (30-300 mg/day), the earliest sign of diabetic nephropathy. A urine dipstick only turns positive at ~300 mg/day, so it is far less sensitive; ultrasound and OGTT do not screen for nephropathy.

A
ليش غلط
The urine dipstick becomes trace positive only at about 300 mg of protein per 24 hours (severely increased albuminuria), so it misses early disease.

B
ليش غلط
Nephropathy screening uses a urine albumin-creatinine ratio and serum creatinine/eGFR; renal ultrasound is not a screening test.

C
ليش غلط
The OGTT is a test to diagnose diabetes (2-hour glucose 200 or more after 75 g); this patient already has diabetes, and it does not screen the kidneys.

D
ليش صح
The urine albumin-to-creatinine ratio is the screening test; waiting for a positive urine dipstick means you have waited too long.
