FAQs
What is the normal hemoglobin level for adult males and females?
Adult male: 13 to 17 g/dL. Adult female: 12 to 15 g/dL. Newborns have higher values, 17 to 22 g/dL.
How does Sahli’s acid hematin method work?
Blood is mixed with dilute hydrochloric acid. The acid lyses red blood cells and converts hemoglobin into brown-colored acid hematin. The color intensity is compared with a standard to estimate hemoglobin concentration.
Why is bleeding time measured in coagulation tests?
Bleeding time evaluates platelet function and blood vessel response to injury. It helps detect bleeding disorders and platelet abnormalities.
What is packed cell volume (PCV)?
PCV, also called hematocrit, measures the percentage of blood volume occupied by red blood cells. It is useful in diagnosing anemia and polycythemia.
Which hemoglobin estimation method is most reliable for laboratory use?
The cyanmethemoglobin method is considered the reference method because it gives accurate and stable results. Sahli’s method is simpler but less precise.
