Study of lipid profile from RIQAS quality control sample
1Biochemistry Laboratory, Peerless Hospital & B.K.Roy Research Centre, 360, Panchasayar, 700094 Kolkata.
External quality assessment samples from Randox International Quality Assessment Scheme (RIQAS) can be reliably used for full lipid profile analysis. This pilot study demonstrated accurate and reproducible results, validating RIQAS samples for broader lipid testing applications.
Area of Science:
- Clinical Chemistry
- Laboratory Quality Assurance
Background:
- Laboratories utilize external quality assessment (EQA) schemes for proficiency testing.
- Randox International Quality Assessment Scheme (RIQAS) provides samples for general chemistry analysis, including some lipid parameters.
Purpose of the Study:
- To evaluate the suitability of RIQAS EQA samples for comprehensive full lipid profile analysis.
- To assess the accuracy and reproducibility of full lipid profile testing using EQA samples.
Main Methods:
- A pilot study was conducted using four EQA samples from two RIQAS cycles.
- Full lipid profiles were analyzed over a fifteen-day trial period.
- Results were compared against Randox internal quality control (IQA) samples.
Main Results:
- The pilot study demonstrated satisfactory results for full lipid profile testing.
- Analysis of RIQAS samples yielded accurate and reproducible lipid profile data.
- The trial confirmed the potential of EQA samples for comprehensive lipid analysis.
Conclusions:
- EQA samples from RIQAS are suitable for performing full lipid profile analysis.
- This approach offers a validated method for quality assessment of lipid testing.
- RIQAS samples can be effectively utilized beyond their intended general chemistry parameters for lipid profiling.

Blood Studies for Cardiovascular System III: Serum Lipid Profile
Serum lipids are fats and fatty substances in the blood and are crucial for various bodily functions, including energy storage, cellular structure, and hormone production. Serum lipids consist of cholesterol, triglycerides, and phospholipids.
Cholesterol is a soft, fat-like substance found in all body cells. It is crucial for producing hormones, vitamin D, and substances that aid...
