Factitious biochemical measurements resulting from hematologic conditions

Area of Science:

• Pathology
• Clinical Chemistry
• Hematology

Background:

• Factitious laboratory results can mimic true pathology, leading to misdiagnosis.
• Preexisting hematologic conditions are a known source of spurious biochemical findings.
• Misinterpretation of these results can result in inappropriate patient management and increased healthcare costs.

Purpose of the Study:

• To review the mechanisms causing factitious biochemical results in patients with hematologic conditions.
• To provide guidance for pathologists on identifying and preventing these laboratory errors.
• To reduce unnecessary diagnostic and therapeutic interventions stemming from factitious results.

Main Methods:

• Literature review focusing on biochemical interferences in hematology.
• Analysis of case studies illustrating factitious laboratory findings.
• Discussion of diagnostic strategies for differentiating factitious from true abnormalities.

Main Results:

• Identified common hematologic conditions associated with factitious biochemical results.
• Described specific mechanisms, such as pseudohyperkalemia or pseudoleukocytosis.
• Highlighted the critical role of pathologist vigilance in error detection.

Conclusions:

• Pathologists play a key role in identifying and mitigating factitious laboratory results.
• Understanding the underlying mechanisms is crucial for accurate diagnosis.
• Implementing preventative measures can improve patient safety and healthcare efficiency.
