An Introduction to the Complete Blood Count for Clinical Chemists: White Blood Cells

|
By van Wijk, Xander M R, Herrera Rivera
| Oxford Academic Verified
The most frequently ordered laboratory test worldwide is the complete blood count (CBC). As clinical chemists are increasingly assigned to assist or direct laboratories outside of the traditional clinical chemistry sections, such as the automated hematology section, expertise must be established. This review article is a dedication to that ongoing effort.

By van Wijk, Xander M R
| Clinical Chemistry Verified
On May 6, 2024, the US FDA published its final rule on laboratory developed tests (LDTs) in the Federal Register (1). Most of the document is considered a preamble discussing background/justification, a phase-out policy of enforcement discretion, and the FDA’s responses to public comments on the proposed rule. The final rule itself is essentially a 10-word addition to the definition of in vitro diagnostic products (IVDs) found in the US Code of Federal Regulations.

An Introduction to the Complete Blood Count for Clinical Chemists: Red Blood Cells

|
By van Wijk, Xander M R
| Oxford University Press (OUP)
The most frequently ordered laboratory test worldwide is the complete blood count (CBC). In this primer, the red blood cell test components of the CBC are introduced, followed by a discussion of the laboratory evaluation of anemia and polycythemia. As clinical chemists are increasingly tasked to direct laboratories outside of the traditional clinical chemistry sections such as hematology, expertise must be developed. This review article is a dedication to that effort.
