The turbid specimen as an analytical medium: hemoglobin determination as a model
Summary
Quantifying analytes in lipemic samples is challenging. Enzymic hydrolysis and fatty acid removal offer an efficient alternative to traditional methods for clarifying milky serum for accurate hemoglobin assays.
Area of Science:
- Clinical chemistry
- Analytical biochemistry
Background:
- Lipemic samples pose significant challenges for accurate clinical laboratory analysis.
- Current sample clarification methods like ultracentrifugation are time-consuming and cumbersome.
Purpose of the Study:
- To present an efficient alternative method for clarifying lipemic samples.
- To demonstrate the utility of this method for hemoglobin quantification in lipemic blood.
Main Methods:
- Enzymic hydrolysis of triglycerides to break down lipids.
- Chemical removal of liberated non-esterified fatty acids.
- Application of this method for assaying hemoglobin in lipemic samples.
Main Results:
- The described method effectively clarifies lipemic serum.
- Accurate hemoglobin quantification was achieved in severely lipemic samples using this approach.
Conclusions:
- Enzymic hydrolysis combined with fatty acid removal provides an efficient and effective alternative for lipemic sample clarification.
- This technique simplifies the process and enables reliable analysis of analytes like hemoglobin in challenging sample matrices.
