Anemia Laboratory Diagnostic Tests Quiz

CBCs are typically collected using lavender top tubes as they contain the necessary anticoagulant to prevent clotting, allowing for accurate blood cell counts.

Erythropoiesis is the process by which red blood cells are produced. It begins with liver cells sensing low oxygen levels and releasing erythropoietin, which stimulates the production of red blood cells from stem cells in the flat bones, such as the ribs and sternum. The incorrect answers provided do not accurately describe the process of Erythropoiesis.

Erythrocytes, also known as red blood cells, are shaped biconcave to maximize their surface area allowing for efficient gas exchange and deformability to pass through narrow capillaries.

An erythrocyte, commonly known as a red blood cell, has a normal lifespan of 120 days before being removed by the spleen or liver.

The incorrect answers do not directly relate to decreased RBCs. Increased iron levels can actually lead to an increase in RBC production, excessive erythropoiesis would increase RBC count, and high altitude living typically results in increased RBC production to compensate for reduced oxygen levels.

Polycythemia is characterized by an excess of red blood cells in the blood. The correct answer lists primary and secondary causes of this condition, which include polycythemia vera, high altitudes, chronic obstructive lung diseases, smoking, and conditions with very small cells. In contrast, vitamin deficiencies, excessive hydration, and iron deficiency anemia are not direct causes of polycythemia.

Various factors such as age, gender, and the specific laboratory can affect the outcomes of lab work. However, weather conditions, time of the day, and the quality of the sample can also have an impact on the results obtained.

The correct stages of Erythrocyte Development follow a specific order starting from proerythroblast and ending with Erythrocyte after passing through reticulocyte, normoblast, and erythroblast.

Severe changes in White Blood Cells (WBCs), Platelets (Plts), and Red Blood Cells (RBCs) often necessitate further investigation into the bone marrow through a biopsy or aspiration to determine the underlying cause.

The normal RBC values for adult males range from 4.6-6.2 million/mm3, while for adult females it ranges from 4.2-5.4 million/mm3. The incorrect answers provided do not fall within the correct ranges and can easily be identified as incorrect based on the given correct answer.
