Calculations and Reference Ranges

  1. Dilution MathStart hereUpdated

    Dilution calculations connect specimen and diluent volumes, single and serial dilution factors, concentrations, and reported laboratory results.

  2. ASCP BOC Examination Reference RangesUpdated

    ASCP BOC composite ranges cover common chemistry, hematology, body-fluid, and urine results used on the MLS examination.

  3. Core Chemistry CalculationsUpdated

    Core chemistry calculations derive iron-binding measures, bilirubin fractions, lipoprotein cholesterol, protein ratios, absorbance, and transmittance.

  4. Timed Urine and Renal Clearance Calculations

    Timed urine calculations convert concentration and volume into excretion, urine flow, creatinine clearance, and body-surface-area-indexed clearance.

  5. Manual Cell-Counting Calculations

    Manual cell-counting calculations derive corrected leukocyte, chamber, body-fluid, traumatic-tap, and sperm results from counted cells and chamber volume.

  6. Red Cell, Reticulocyte, and Absolute Count Calculations

    Red-cell index, reticulocyte, and absolute-count formulas convert CBC measurements and cell proportions into reportable values with explicit unit and rounding rules.

  7. Clinical Reference Intervals Across Disciplines

    Published examples show how reference intervals change with the population, specimen, method, age, sex, and laboratory setting.
