The CBC comprises several key parameters that are crucial in toxicological evaluations:
Red Blood Cells (RBC): These cells transport oxygen throughout the body. Toxins can cause anemia by reducing RBC count or altering their function. White Blood Cells (WBC): Critical for immune defense, their count can be altered by toxic exposure, indicating infection or immune suppression. Hemoglobin: This protein in RBCs carries oxygen. Toxins such as lead can interfere with hemoglobin production. Hematocrit: This measures the proportion of blood volume occupied by RBCs. Changes may suggest dehydration or anemia due to toxic exposure. Platelets: Essential for blood clotting, exposure to certain toxins can lead to thrombocytopenia, increasing bleeding risk.
