How this service works
Martin 2013 estimated LDL-C from total cholesterol, HDL, and triglycerides in mg/dL. Adjustable TG:VLDL-C factor from the published 180-cell table by non-HDL-C and TG strata. Not Friedewald factor 5, not Sampson, not a diagnosis or statin order.
Output
Returns an estimated LDL-C value in mg/dL computed via the Martin 2013 method, using the appropriate TG:VLDL-C conversion factor from the 180-cell table indexed by non-HDL-C and triglyceride strata. Does not return a diagnosis or treatment recommendation.
Example use cases
Lipid panel LDL estimation for clinical review
“I have a patient's lipid panel: total cholesterol 230 mg/dL, HDL 48 mg/dL, triglycerides 175 mg/dL — can you estimate their LDL using the Martin 2013 method with the adjusted TG:VLDL factor?”
Comparing Martin vs Friedewald in borderline TG range
“My patient has total cholesterol 195 mg/dL, HDL 42 mg/dL, and triglycerides 310 mg/dL — use the Martin 2013 table-based method to estimate LDL since Friedewald isn't ideal at higher triglyceride levels.”
Automated lipid report enrichment pipeline
“For the following lipid values — total cholesterol 178 mg/dL, HDL 61 mg/dL, triglycerides 88 mg/dL — calculate LDL-C using the Martin 2013 adjustable factor approach and include the non-HDL-C and TG stratum used.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/martin_ldlWhen to prefer
Use this endpoint when you need LDL-C estimation via the Martin 2013 method specifically — particularly when triglycerides are elevated enough to make the Friedewald factor-of-5 less accurate, but still below 400 mg/dL. Prefer this over Friedewald when you want stratum-adjusted TG:VLDL-C factors from the published 180-cell table. Do not use for triglycerides >= 400 mg/dL (use Sampson or direct LDL measurement instead), and do not use for mmol/L inputs.
Side effects
- Triglycerides >= 400 mg/dL are rejected — the Martin 2013 paper excludes this range
- HDL >= total cholesterol causes rejection because non-HDL-C would be zero or negative
- Values outside stated ranges (TC 50-500, HDL 5-150, TG 7-399) return validation errors
- Missing any of the three required query parameters returns an error
- mmol/L inputs are not converted and will produce incorrect results if submitted as mg/dL
