About the test
This test is a crucial screening tool for identifying various conditions, including leukemia and inflammation. It measures the number of white blood cells in the blood, which are vital for fighting infections and diseases.
Who might consider it:
This test may be recommended if patients show symptoms of infection or inflammation.
Common Symptoms:
- Fever
- Weakness or fatigue
- Unexplained weight loss
- Frequent infections
- Bruising or bleeding easily
Included biomarkers & Reference ranges
| Biomarker | Reference range |
|---|---|
| Basophils (%) The percentage of your white blood cells that are basophils, a cell type involved in allergic and inflammatory responses. | — |
| Eosinophils (%) The percentage of your white blood cells that are eosinophils, elevated with allergies, asthma, or parasitic infections. | — |
| Lymphocytes (%) The percentage of your white blood cells that are lymphocytes, key immune cells including T-cells, B-cells, and NK cells. | — |
| Monocytes (%) The percentage of your white blood cells that are monocytes, cells that help fight infection and clear damaged tissue. | — |
| Neutrophils (%) The percentage of your white blood cells that are neutrophils, a first-line defense against infection. | — |
| Band Neutrophils (%) Shows band neutrophils, young infection-fighting white blood cells, as a percentage of all your white blood cells, which can rise with infection or inflammation. | — |
| Band Neutrophils Counts the number of band neutrophils, young infection-fighting white blood cells, per volume of blood, which can rise with infection or inflammation. | — |
| Basophils The number of basophils, a type of white blood cell involved in allergic and inflammatory responses, in your blood. | — |
| Blasts (%) Shows blasts, very immature blood cells, as a percentage of your white blood cells, reported as part of a full differential blood count. | — |
| Blasts Counts the number of blasts, very immature blood cells, in your blood sample as part of a full differential blood count. | — |
| Eosinophils The number of eosinophils, a white blood cell type involved in allergic reactions and parasite defense, in your blood. | — |
| Lymphocytes The number of lymphocytes, white blood cells central to your immune response (including T-cells, B-cells, and NK cells), in your blood. | — |
| Metamyelocytes (%) The percentage of your white blood cells that are metamyelocytes, an immature white blood cell normally confined to the bone marrow. | — |
| Metamyelocytes The absolute number of metamyelocytes, immature white blood cells normally found in bone marrow, in your blood as part of a differential count. | — |
| Monocytes The number of monocytes, white blood cells that help fight infection and clear damaged cells, in your blood. | — |
| Myelocytes (%) The percentage of your white blood cells that are myelocytes, early immature white blood cells normally confined to the bone marrow. | — |
| Myelocytes The absolute number of myelocytes, early immature white blood cells normally found only in bone marrow, in your blood. | — |
| Neutrophils The number of neutrophils, the most abundant white blood cell type and a first-line defense against infection, in your blood. | — |
| Nucleated RBC (%) The number of nucleated red blood cells, immature red cells not normally seen in adult blood, expressed relative to your white blood cells. | — |
| Nucleated RBC The absolute number of nucleated red blood cells, immature red cells not normally seen in adult blood, as part of a blood count. | — |
| Promyelocytes (%) The percentage of your white blood cells that are promyelocytes, immature cells normally found only in bone marrow, reported as part of a differential. | — |
| Promyelocytes The absolute number of promyelocytes, immature white blood cells normally found only in bone marrow, in your blood, reported as part of a differential. | — |
| Reactive Lymphocytes Reports lymphocytes that look activated under the microscope, a common sign that your immune system is responding to an infection, especially a viral one. | — |
| White Blood Cell Count (WBC) White blood cell count — the total number of white blood cells in your blood, key immune cells. Used to help detect infection, inflammation, and other blood disorders. | — |
