IBEX Sciences Hemoglobin (Hb) Reagent Solution (Ready for Use) is a pre-formulated liquid chemical solution used in clinical and diagnostic laboratories for the qualitative or quantitative determination of hemoglobin levels in whole blood samples. [1, 2, 3]
Key Characteristics & Features
- Ready-to-Use (RTU): The reagent is supplied pre-mixed to the exact concentration required for diagnostic tests. Laboratories do not need to undergo complex formulation, reconstitution, or dilution processes, reducing preparation errors and saving time. [1, 2, 3, 4]
- Methodology: Most ready-to-use hemoglobin reagents utilize the classic Cyanmethemoglobin (Drabkin’s) method or automated colorimetric equivalents. In this process, hemoglobin is oxidized and converted into a stable compound (cyanmethemoglobin), which is then measured photometrically at a wavelength of 540 nm to determine blood concentration. [1, 2, 3, 4, 5]
- Application: It is suitable for manual spectrophotometers as well as semi-automated or fully automated biochemistry analyzers. [1, 2, 3, 4, 5]
Specifications & Storage Guidelines
- Storage Temperature: Typically stored at room temperature (15°C to 25°C), away from direct sunlight, depending on manufacturer specifications. [1, 2, 3]
- Stability: Highly stable until the expiration date printed on the bottle if left unopened. Once opened, it usually maintains stability for several months provided contamination is avoided. [1, 2]
- Signs of Deterioration: The solution should not be used if it develops turbidity, forms a precipitate, or changes from its standard yellow color. [1]
Important Safety Precautions
- Contains Cyanide: Because standard Drabkin’s formulations contain small amounts of potassium cyanide, it is a toxic substance if swallowed. Never pipette this solution by mouth.
- Acid Incompatibility: Keep the reagent entirely away from acids. Mixing it with an acid liberates highly toxic hydrogen cyanide gas.
- Disposal: Spent or unused reagent must be discarded with large volumes of water or in accordance with your laboratory’s hazardous chemical waste protocols. [1, 2, 3, 4]
