Determination of Hemoglobin, Hematocrit Value, and Calculation of Blood Indices

Flashcards to help prepare for the exam on hemoglobin determination, hematocrit values, and blood indices.

What method is used to assess Hb concentration?

The cyanmethemoglobin method.

What is the definition of hematocrit value (Hct)?

The percentage ratio of red blood cells in the total blood.

What are the normal values for adult male Hb concentration?

16 +2 gm/dl.

What can a Complete Blood Count (CBC) test detect?

Blood cancers, anemia, and infections.

What are the causes of leukopenia?

Bone marrow depression, AIDS, and immunosuppressive drugs.

What does an increased RDW indicate?

That red blood cells are more variable in volume than normal.

What is the normal range for total leukocytic count?

4,000-11,000/mm³.

What test measures the average volume of red blood cells?

Mean Corpuscular Volume (MCV).

What does Polycythemia indicate?

Increased RBC count.

What can cause thrombocytopenia?

Bone marrow depression, autoimmune disease, splenomegaly.

What are the main types of hemoglobin?

HbA, HbA2, and HbF.

What is the normal range for MCHC?

30-35 g/100 ml of RBCs.

What does a high MCHC indicate?

That red blood cells have a higher concentration of hemoglobin.

What type of anemia is associated with low MCV?

Microcytic anemia.

What is assessed in the differential leukocytic count?

The proportions of different types of white blood cells (WBCs).

What are the normal values for adult female Hb concentration?

14 \pm 2 gm/dl.

What does leukocytosis indicate?

An increase in total white blood cell count above 11,000/mm^3, often a sign of infection, inflammation, or stress.

What does thrombocytosis indicate?

An increase in platelet count above normal levels, potentially associated with inflammation, infection, or certain blood disorders.
