U.S. and SI units
Units and conversions

Choose the unit printed by the laboratory. Switching units converts the current value and its reference limits; it does not change the quantity.

  • Hemoglobin and MCHC: 1 g/dL = 10 g/L.
  • Hematocrit: 40% = 0.40 L/L.
  • WBC, platelets and absolute differential: 1 ×10³/µL = 1 ×10⁹/L = 1,000 cells/µL.
  • RBC: 1 million/µL = 1 ×10¹²/L.
  • MCV, MPV and RDW-SD use fL; MCH uses pg; RDW-CV uses %.

Analysis and exported comparisons use U.S. conventional units. Percentage differentials are converted using WBC.

Example intervals: University of Iowa. Use the performing laboratory’s intervals when available.

Pattern needs clinician review

A supported pattern raises a focused follow-up question.

Low hemoglobin, microcytic pattern

Hemoglobin10.2Hematocrit32.3Red blood cells4.75MCV68RDW-CV18.2

Hemoglobin is below the selected laboratory interval. MCV and RDW help frame the differential; they do not determine the cause.

Possible considerations
  • Iron deficiency
  • Thalassemia or another hemoglobinopathy
  • Anemia of inflammation
  • Sideroblastic processes

Unranked possibilities for clinician review, not predicted diagnoses.

The <8 g/dL intermediate review threshold is a prototype policy; only explicitly named critical triggers use institutional notification limits.

Small mean cell volume, interpreted with RBC and RDW

MCV68Red blood cells4.75Hemoglobin10.2RDW-CV18.2

MCV 68 fL meets the commonly used <80 fL morphology convention. A preserved or increased RBC count can coexist with microcytosis; compare iron status and hemoglobinopathy history.

Possible considerations
  • Iron deficiency
  • Thalassemia or another hemoglobinopathy
  • Anemia of inflammation
  • Lead exposure
  • Sideroblastic processes

Unranked possibilities for clinician review, not predicted diagnoses.

No adult Mentzer cutoff is used. Coexisting iron deficiency and thalassemia cannot be separated by these indices alone.

Raised platelets in the rest of the panel

Platelets465Hemoglobin10.2MCV68White blood cells6.8

Low hemoglobin, microcytosis and raised platelets can occur with iron deficiency, but do not establish it.

Possible considerations
  • Reactive thrombocytosis
  • Iron deficiency
  • Inflammatory conditions
  • Myeloproliferative neoplasms

Unranked possibilities for clinician review, not predicted diagnoses.

Other values outside the selected intervals

MCH21.5MCHC31.6

These interval flags need context and should not be treated as independent diagnostic votes.

Reference review is a prototype policy, not a diagnosis or a validated urgency threshold.

Scope, uncertainty and limitations

No positive smear finding was entered. Morphology, blasts and schistocytes cannot be inferred from numeric CBC values.

Priority is an unvalidated review-queue aid, not a diagnosis, disease probability, treatment recommendation or reassurance about symptoms.

No generic high-normal multiplier or diagnostic NLR/PLR cutoff is used. Reference intervals and disease-specific criteria are different concepts.
