Automated hematology analyzers have revolutionized blood diagnostics, and at their heart lies the precise action of specialized reagents. Among these, lyse reagents are critical for enabling accurate blood cell analysis. NINGBO INNO PHARMCHEM CO.,LTD. explains the scientific underpinnings of these vital components, illustrating the purpose of lyse reagent in blood test and the science that makes it work.

The fundamental mechanism of a lyse reagent is cell lysis, specifically targeting red blood cells (RBCs). Blood is a complex fluid containing various cell types, with RBCs being the most abundant. For accurate counting and analysis of white blood cells (WBCs) and for measuring hemoglobin (HGB), the overwhelming presence of RBCs must be addressed. This is where the lyse reagent comes into play.

Lyse reagents are typically aqueous solutions containing specific chemical components. The most common active ingredients include surfactants, which are molecules with both hydrophilic (water-attracting) and hydrophobic (water-repelling) properties. These surfactants work by disrupting the lipid bilayer of the RBC membrane. They can embed themselves into the membrane, weakening its structure and eventually causing it to break apart. This process releases the contents of the RBC, including hemoglobin, into the surrounding solution.

The effectiveness of lysis is influenced by several factors, including the concentration of the surfactant, the pH of the solution, and its osmolarity. A well-formulated lyse reagent will efficiently lyse RBCs without damaging WBCs, thus preserving their integrity for counting and differentiation. Some reagents are designed to be 'iso-lytic,' meaning they lyse RBCs while maintaining the normal size and shape of WBCs, which is crucial for accurate WBC counting and differential analysis.

Once RBCs are lysed and hemoglobin is released, the resulting solution can be analyzed. For hemoglobin measurement, the released hemoglobin reacts with specific chemicals in the reagent or a subsequent reagent to form a colored compound. The intensity of this color, measured by a spectrophotometer, is directly proportional to the hemoglobin concentration in the original sample. This demonstrates the critical role of understanding hematology analyzer lyse reagent use.

For WBC counting, the analyzer's system detects and counts the cells that are not lysed. By removing the far more numerous RBCs, the system can distinguish and count the much smaller population of WBCs with high accuracy. For those looking to buy hematology lyse reagent online, understanding these scientific principles ensures the selection of products that are scientifically sound and effective for their intended application.

The science behind lyse reagents is a sophisticated interplay of chemistry and biology, enabling the detailed insights provided by hematology analyzers.
