1Hamad Medical Corporation, Doha, State of Qatar.
Insights
Internal quality control ensures laboratory result validity. This study assessed the stat service at Hamad Medical Corporation, confirming reliable diagnostic testing for inpatients.
Area of Science:
- Clinical Chemistry
- Laboratory Medicine
- Quality Assurance
Background:
- Laboratory result validity is crucial for patient care.
- Internal and external quality control systems are essential for accurate diagnostics.
- This study focuses on the internal quality check of the stat service at Hamad Medical Corporation.
Purpose of the Study:
- To evaluate the internal quality control of the stat laboratory service.
- To ensure the reliability and validity of diagnostic results for inpatients.
- To assess the performance of specific chemistry and immunoassay analytes.
Main Methods:
- Internal quality control was performed on nine chemistry analytes (BUN, Na, K, Cl, Ca, Co2, Glucose, Creatinine, Bilirubin) using the Astra VIII auto-analyzer.
- BIORAD Normal and Abnormal (Chemistry Control) and immunoassay levels 1, 2, and 3 were utilized for quality assessment.
- Results within 2 standard deviations (SD) were accepted, adhering to established quality control parameters.
Main Results:
- The 2 SD% for chemistry controls ranged from 61.5% to 85.5% (Normal) and 92.0% to 98.8% (Abnormal).
- For hormone immunoassays, the 2 SD% ranged from 92.7% to 100% across levels 1, 2, and 3.
- These results indicate a high degree of consistency and reliability for the tested analytes.
Conclusions:
- The internal quality control systems demonstrate the reliability of the stat service at Hamad Medical Corporation.
- The study confirms the validity of laboratory results for inpatients, supporting clinical decision-making.
- Continuous quality monitoring is vital for maintaining high standards in diagnostic laboratory services.
Background:
The recognition and validity of laboratory results can better be judged by its internal and external quality control systems. Here we report an internal quality check of the stat service provided to the inpatients at Hamad Medical Corporation, Doha, State of Qatar.
Methods:
Periodic internal quality control of nine chemistry analytes, BUN, Na, K, Cl, Ca, Co2, Glucose, Creatinine and Bilirubin were made on auto-analyzer Astra VIII. BIORAD Normal and Abnormal (Chemistry Control) and immunoassay level 1, 2 and 3 were employed. All results falling with in 2 SD were accepted.
Results:
2 SD% for chemistry Normal and Abnormal ranged from 61.5% to 85.5% and 92.0% to 98.8% and for hormones Immunoassay level 1, 2, and 3 from 92.7% to 100% respectively.
