A series of tests providing information about RBCs, WBCs, and platelets.

Measurements of red blood cells, including MCV, MCH, and MCHC.

Conditions leading to decreased red blood cells or hemoglobin levels.

Ferritin stores iron; both indicate iron status in the body.

Includes neutrophils, lymphocytes, monocytes, eosinophils, and basophils; each with specific functions.

The number of RBCs in 1mm3 of peripheral blood, with reference ranges being 4.7 – 6.1 (male) and 4.2 – 5.4 (female) x10^12/L.

A condition characterized by decreased RBC count, indicating insufficient oxygen transport in the blood.

A type of anemia where large, immature RBCs are produced due to impaired DNA synthesis, commonly from Vit B12 or folate deficiency.

A condition with small RBCs, often due to iron deficiency, leading to inadequate oxygen transport.

A deficiency of all blood cell types (RBCs, WBCs, platelets), often caused by aplastic anemia.

Indicates the size of red blood cells; used in anemia classification.

Anemias caused by B12 or folic acid deficiency; characterized by increased MCV.

Measures the variation in RBC sizes; aids in classifying anemias.

Number of white blood cells in a blood sample; normal range is 5,000-10,000/mm3.

Increase in WBC count; commonly points to infection or inflammation.

Immature red blood cells indicating bone marrow activity.

Normal range for reticulocytes in adults is 0.5% - 2.0%.

Indicates the marrow is producing more RBCs due to loss.

Suggests inadequate bone marrow response in anemic patients.

Protein in RBCs that carries oxygen; reference range for males is 14-18 g/dL, for females is 12-16 g/dL.

Percentage of blood volume made up of RBCs; male reference: 42-52%, female: 37-47%.

Number of platelets per cubic mm; normal range is 150,000-400,000/mm3.

Average size of red blood cells; important in classifying RBC size abnormalities.

An increase in immature neutrophils (bands) indicating bacterial infection.

A return to normal neutrophil counts from a left shift, indicating recovery or stabilization.

An increase in neutrophils without immature forms, possibly indicating inflammation without infection.

Lymphocytes constitute 20-40% of WBCs, involved in chronic bacterial or acute viral infections.

Neutrophils with 6 or more lobes, sensitive to megaloblastic anemias (B12/folic acid deficiency).

WBC cancer classified into acute (immature WBCs) and chronic (mature WBCs), both with high WBC counts.

Structures found in acute myeloid leukemia (AML), indicating a specific type of cancer.

Cancers originating from lymphocytes, with various subtypes and presentations.

A type of cancer marked by Reed-Sternberg cells; 10% of lymphoma cases.

A type of lymphoma accounting for 90% of cases; varied forms without Reed-Sternberg cells.

Serum iron, TIBC, transferrin saturation, ferritin; assesses iron levels in the body.

Iron found in hemoglobin; 70% in RBCs, 30% stored as ferritin.

Measure of proteins available to bind iron, primarily transferrin.

Percentage of TIBC that is saturated with iron; indicates body's iron status.

Major storage protein for iron; low levels indicate deficiency, high levels indicate excess.

Rate at which RBCs settle; increased in inflammation or infection.

Acute phase reactant protein indicating inflammation; responds quickly to changes.

Includes bleeding time, PT/INR, PTT; assesses hemostatic function.
