Summary
This study establishes reference values for bronchoalveolar lavage (BAL) fluid analysis, including cytologic and biochemical markers. These findings aim to standardize BAL interpretation for diagnosing various lung diseases.
Area of Science:
- Pulmonology
- Clinical Diagnostics
- Biochemistry
Context:
- Bronchoalveolar lavage (BAL) is a key diagnostic tool in pulmonology.
- Lack of standardization and reference values hinders consistent BAL interpretation.
- International standards have addressed technique standardization, but a reference BAL is still needed.
Purpose:
- To establish reference values for bronchoalveolar lavage (BAL) fluid.
- To analyze both cytologic and biochemical components of BAL fluid.
- To create a standardized reference for BAL analysis in clinical practice.
Summary:
- Analyzed 203 BAL samples from control and patient groups (asthma, infections, interstitial lung diseases, tumors, chronic bronchitis).
- Measured cytologic components (macrophages, lymphocytes, neutrophils, eosinophils) and biochemical markers (CEA, TPA, NSE, FER, CT, ACTH, HIS, PGE2).
- Utilized modified Bayes' theorem to determine reference values for BAL components.
Impact:
- Provides a standardized reference for bronchoalveolar lavage (BAL) fluid analysis.
- Aids in more accurate diagnosis and management of respiratory diseases.
- Facilitates consistent interpretation of BAL results across different clinical settings.
