How this service works
Adult maximum normal erythrocyte sedimentation rate (mm/h, 98th percentile approximation) from age and sex (Miller 1983). Men: age/2. Women: (age + 10)/2. Deterministic published arithmetic with citation. Returns the threshold only; not a diagnosis, not a measured ESR, and not Wener 2000 CRP. magent does not measure ESR.
Output
Returns the calculated upper limit of normal ESR in mm/h (98th percentile approximation) for the given age and sex, using the published Miller 1983 formulas: men = age/2, women = (age+10)/2. This is a reference threshold value only — not a diagnosis, not a measured ESR value, and not based on CRP or any other marker.
Example use cases
Flag elevated ESR in clinical report
“I'm reviewing a lab result for a 72-year-old male with an ESR of 42 mm/h — what's the Miller 1983 upper limit of normal for his age and sex so I can tell if that's elevated?”
Age-adjusted ESR threshold for elderly woman
“What's the maximum normal ESR for an 80-year-old female according to the Miller 1983 formula?”
Confirm ESR cutoff for middle-aged male
“My patient is a 50-year-old man. What ESR value should I use as the upper threshold of normal based on age and sex using the Miller 1983 rule?”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/miller_esrWhen to prefer
Use this endpoint when you need the Miller 1983 age- and sex-adjusted ESR upper limit of normal for an adult patient (ages 20–90). It is the right choice when you need a quick, deterministic, evidence-based reference threshold rather than a diagnosis or a measured ESR result. Prefer this over general medical knowledge lookups when you need a citable, formula-based value with a known provenance (Miller 1983 publication). Do not use this to measure ESR, interpret CRP, or handle pediatric patients.
Side effects
- Age outside the 20-90 adult range may return an error or out-of-range response
- Invalid or missing 'sex' enum value (must be 'male' or 'female') will cause a validation error
- Non-integer age values will be rejected by the schema
- Missing required query parameters (age or sex) will result in a request error
- Payment failure (x402) will block the response
