In which type of anemia are RBCs normocytic and normochromic, with decreased RBCs, hemoglobin, and hematocrit, and increased indirect bilirubin?

In hemolytic anemia, red blood cells (RBCs) are typically normocytic and normochromic due to the nature of the condition. In this type of anemia, the body’s production of RBCs is adequate; however, there is an increased destruction of these cells. This destruction leads to a decrease in the overall number of RBCs, hemoglobin, and hematocrit levels, resulting in anemia.

The increase in indirect bilirubin is particularly indicative of hemolytic anemia. When RBCs are broken down, hemoglobin is released and subsequently broken down into bilirubin. Since the liver can become overwhelmed with this process, the bilirubin accumulates, causing an increase in indirect bilirubin levels in the bloodstream.

In contrast, other forms of anemia involve different mechanisms. For example, ineffective erythropoiesis results in abnormal RBCs being produced, often leading to macrocytic cells and decreased hemoglobin or hematocrit due to inadequate production, not destruction. Iron deficiency anemia typically presents with microcytic, hypochromic red blood cells, and vitamin B12 deficiency anemia generally leads to macrocytic cells as well, with distinctive neurologic symptoms due to deficiency in B12, rather than a hemol
