Understanding Advanced Hematologic Testing

  • Chapter
  • First Online:
Hematologic Challenges in the Critically Ill

Abstract

Critically ill patients undergo numerous laboratory tests to better understand their disease processes and track their illnesses. Many critically ill patients have a variety of conditions such as anemia, sepsis, multiorgan failure, coagulopathies, and/or infection. For the patient to receive the correct diagnosis and treatment, laboratory tests must be carefully ordered and interpreted. Laboratory testing pertaining to anemia, thrombocytopenia, sepsis, bleeding, and hypercoagulability will be discussed in this chapter. Testing interferences as well as caveats that are important to recognize in test result interpretation will be addressed. Moreover, recent advances in hematologic testing of critically ill patients for anemia and coagulopathies such as the reticulocyte hemoglobin, chromogenic factor Xa assay, chromogenic factor VIII assay, TEG platelet mapping, and anti-Xa assay will be discussed in detail.
