Clinical chemistry since 1800: growth and development.

Area of Science:

• Clinical Chemistry
• Medical Laboratory Science
• History of Medicine

Background:

• The 19th and 20th centuries saw significant growth in clinical chemistry, yet contributions of many pioneers remain underappreciated.
• Early figures like Fourcroy, Berzelius, and Liebig laid groundwork, while Folin and Van Slyke advanced the field, integrating it with patient care.
• The Abraham Flexner report and World War I accelerated the adoption of laboratory medicine.

Observation:

• The late 20th century experienced over-reliance on automated testing, sometimes overshadowing clinical examination and patient history.
• A growing recognition of chemical diagnostics' value highlighted the need for closer partnerships between clinicians and clinical chemists.
• Automation led to an overabundance of testing, potentially impacting the quality of patient assessment.

Findings:

• Key historical figures and their contributions are often overlooked by new professionals in clinical chemistry.
• The integration of clinical chemistry into patient care evolved significantly due to pivotal reports and global events.
• Automation in the late 20th century presented challenges, including overuse and misuse of tests.

Implications:

• Understanding historical context is crucial for current clinical chemists to appreciate the field's evolution.
• There is a need to re-emphasize the synergy between laboratory data interpretation and direct patient assessment.
• Clinical chemists must evolve their services to provide diagnostically relevant interpretations, fostering stronger clinician partnerships.
