Which one do you need?
- Anion Gap Calculator
- Calculate the serum anion gap, correct it for albumin, and read the delta ratio and corrected bicarbonate to separate high-gap, normal-gap and mixed acidosis.
- Corrected Calcium for Albumin Calculator
- Adjust total serum calcium for albumin using the Payne formula. Get corrected calcium in mg/dL and mmol/L, the size of the correction, and what the value means.
- Serum Osmolality & Osmolal Gap Calculator
- Calculate serum osmolality from sodium, glucose and BUN, compare it against the measured value, and read the osmolal gap to screen for toxic alcohols.
- eGFR Calculator (CKD-EPI 2021)
- Estimate GFR with the race-free CKD-EPI 2021 creatinine equation, add cystatin C for confirmation, compare MDRD, and read the KDIGO stage and de-indexed clearance.
- Creatinine Clearance Calculator (Cockcroft-Gault)
- Estimate creatinine clearance by Cockcroft-Gault using total, ideal and adjusted body weight, compare it with a timed urine collection, and see which weight to dose on.
