Calculates MCV, MCH, and MCHC from hemoglobin, hematocrit, and RBC count.

Calculates an absolute white cell count (e.g. ANC, ALC) from total WBC and differential percentage.

Corrects the total WBC count for the presence of nucleated red blood cells (nRBCs).

Estimates hematocrit from hemoglobin using the commonly cited 'rule of three'.

Adjusts the reticulocyte percentage for the patient's hematocrit and an explicit maturation correction.

Calculates INR from prothrombin time, laboratory mean normal PT, and the reagent ISI.

Calculates the ratio of patient activated partial thromboplastin time to the laboratory control or mean normal aPTT.

Calculates platelet corrected count increment after transfusion using platelet increment, body surface area, and platelet dose.

Estimates packed red-cell volume from an estimated blood volume, current and target hematocrit, and product hematocrit.

Estimates circulating blood volume from body weight using an explicitly selected adult estimate.

Calculates the five-factor International Prognostic Index used in aggressive non-Hodgkin lymphoma risk assessment.

Calculates the five-factor revised IPI score using age, stage, LDH, performance status and extranodal disease.
