% CD8-/CD57+ NK Cells details
What % CD8-/CD57+ NK Cells shows
This measures the percentage of your lymphocytes that fall into this specific natural killer cell subset (CD8-negative, CD57-positive), used alongside the absolute count in specialized immune function assessments. As with the absolute count, it's ordered in specific clinical contexts — sometimes as part of chronic infection or complex immune evaluations — rather than as a routine or standalone screening marker, and its interpretation is generally guided by the ordering practitioner's specific clinical question.
Tests that include % CD8-/CD57+ NK Cells
The HNK1 (CD57) Profile is used to monitor the CD57 lymphocyte subset in patients with chronic Lyme disease.
Biomarkers
- Basophils (%) The percentage of your white blood cells that are basophils, a cell type involved in allergic and inflammatory responses.
- CD8-/CD57+ NK Cell Count Counts a specific subset of natural killer cells sometimes used in specialized immune function testing, including chronic infection evaluations.
- Eosinophils (%) The percentage of your white blood cells that are eosinophils, elevated with allergies, asthma, or parasitic infections.
- Hematocrit The percentage of your blood volume made up of red blood cells. Used to help diagnose anemia or polycythemia (excess red blood cells).
- Hemoglobin The oxygen-carrying protein in your red blood cells. A core marker for diagnosing anemia and other blood disorders.
- Immature Granulocytes (%) The percentage of young, not-yet-mature white blood cells in circulation — a rise can be an early sign of infection or bone marrow stress.
- 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.
- % CD8-/CD57+ NK Cells The percentage of lymphocytes that are this natural killer cell subset, used in specialized immune function assessments.
- Basophils The number of basophils, a type of white blood cell involved in allergic and inflammatory responses, in your blood.
- Eosinophils The number of eosinophils, a white blood cell type involved in allergic reactions and parasite defense, in your blood.
- Immature Granulocytes The number of young, not-yet-mature white blood cells in circulation — a rise can be an early sign of infection or bone marrow stress.
- Lymphocytes The number of lymphocytes, white blood cells central to your immune response (including T-cells, B-cells, and NK cells), in your blood.
- Mean Corpuscular Hemoglobin Concentration (MCHC) Mean Corpuscular Hemoglobin Concentration — the average concentration of hemoglobin within your red blood cells, used to help classify types of anemia.
- Mean Corpuscular Hemoglobin (MCH) Mean Corpuscular Hemoglobin — the average amount of hemoglobin per red blood cell, used to help classify types of anemia.
- Mean Corpuscular Volume Mean Corpuscular Volume — the average size of your red blood cells, a key value used to help determine the cause of anemia.
- Monocytes The number of monocytes, white blood cells that help fight infection and clear damaged cells, 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 (%), Automated An automated count of nucleated red blood cells, immature red cells not normally seen in adult blood, reported relative to white blood cells.
- Platelet Count Cell fragments that help your blood clot. Counted to screen for bleeding or clotting risk and various blood disorders.
- Red Blood Cell Count (RBC) Red blood cell count — the number of oxygen-carrying red blood cells in your blood, used to help diagnose anemia or polycythemia.
- Red Cell Distribution Width (RDW) Red Cell Distribution Width — measures how much your red blood cells vary in size, helpful for narrowing down the cause of anemia.
- 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.
