by magent in Other

x402 APIFailing, checked 5 h ago

AKIN 2007 (Mehta Table 2) stage 0-3 from baseline and current creatinine in mg/dL and a caller-assigned urine-output category. Stage is the worse of the two limbs; RRT is stage 3. magent does not assay creatinine, measure urine, or collect weight. Not a medical device, not a diagnosis, not KDIGO 2012, and not RIFLE.
