What is the procedure of cyanmethemoglobin?
Blood and Drabkins Reagent (RBCs lysed and Hgb released) Hgb oxidized to methoglobin by K ferricyanide Resulting pigment converted to stable cyanmethoglobin by Kcyanide Absorption of pigment measured photometrically at 540nm Concentration of Hgb is directly proportional to optical density of solution
What is the significance of the development of the cyanmethemoglobin method?
The development of the cyanmethemoglobin method is significant in hematology and clinical medicine because it allows for accurate measurement of hemoglobin levels in blood samples. This method is considered more reliable than older techniques and has become a standard in blood testing due to its precision and reproducibility. It is particularly important for diagnosing and monitoring conditions such as anemia and other blood disorders.
Hb estimation by drabkin's method?
Drabkin's method is a commonly used laboratory technique to estimate hemoglobin levels in the blood. It involves lysing the red blood cells to release hemoglobin and then measuring the absorbance of the hemoglobin-cyanmethemoglobin complex at a specific wavelength to determine the concentration of hemoglobin in the sample. This method provides a quick and accurate assessment of hemoglobin levels, which is crucial for diagnosing conditions like anemia.
What is the principle of aluminium chloride method?
The principle of the aluminium chloride method involves using aluminium chloride as a catalyst to promote the Friedel-Crafts acylation or alkylation reaction. This method is commonly used in organic chemistry to introduce new functional groups onto aromatic compounds. The aluminium chloride coordinates with the electrophile and enhances its reactivity towards the aromatic ring.
What is the principle of agar diffusion method?
The principle of agar diffusion method is based on the diffusion of an antimicrobial agent from a sample into an agar medium containing a test organism. The size of the zone of inhibition that forms around the sample is used to determine the effectiveness of the antimicrobial agent against the test organism.
Disadvantages using cyanmethemoglobin method?
three disadvantages cyanmethemoglobin
Advantages and disadvantages using cyanmethemoglobin method?
The Cyanmethemoglobin method is a commonly used laboratory procedure for the estimation of hemoglobin in blood. This method has several advantages and disadvantages. Advantages: Accuracy: The Cyanmethemoglobin method is considered very reliable and is often used as a reference method. Stability: The Cyanmethemoglobin solution is stable, and readings can be taken at a later time without significant alteration. Interference: It is less susceptible to turbidity and lipemia interference as compared to other methods. Disadvantages: Toxicity: The reagent used, Drabkin's solution, contains potassium cyanide, which is toxic and needs to be handled with care. Time: The reaction time to obtain cyanmethemoglobin is relatively longer compared to other methods. Interference: The method can overestimate hemoglobin if a large number of white cells, such as in leukemias, are present. In conclusion, while the Cyanmethemoglobin method has its advantages, including accuracy and stability, it also has some disadvantages such as toxicity of the reagent used and potential interference in certain conditions. It's crucial to carefully consider these factors before deciding on a method for hemoglobin estimation.

Which are the Methods for hemoglobin estimation?
Hemoglobin estimation is the measuring of hemoglobin levels that are broken into three categories. Visual methods are Sahil, Dares, Hadens, Wintrobes, Haldanes, Tallquists method. Second to consider are the gasometric method, single to the Van Slyke method. Lastly the spectrophotometric method oxyhemoglo, and the cyanmethemoblobin method.
