Laboratory Variables Relevant to Hematologic Diagnosis (Normal Adult Values)
Values in infancy and childhood are not included (see Chap. 1 of this Manual and Chap. 7 of Williams Hematology, 8th Edition, 2011). The normal ranges described here are guidelines. They may vary from laboratory to laboratory and some lower and upper limits are still disputed. They vary based on reagents, assay and instruments used. Normal values should be established in the laboratory of record. This requirement is especially true of determinations such as prothrombin and thromboplastin time, D-dimer assay, platelet aggregometry, platelet ATP release, and others.
