Basophil Count details

Description

Basophils are the least common type of white blood cell, making up typically less than 1-2% of your total white blood cell count, and they play a role in allergic reactions and inflammatory responses, releasing histamine and other chemicals similar to mast cells. This test counts the actual number of basophils in your blood as part of a complete blood count (CBC) with differential. Elevated basophil counts are relatively uncommon but can occur with allergic reactions, certain chronic inflammatory conditions, hypothyroidism, or — more rarely — certain blood disorders including some types of leukemia, where basophil counts can be markedly elevated. Because basophils are normally so few in number, small changes carry less significance than similar changes in more abundant white blood cell types.

$35.50

This panel checks key markers to see if the patient has levels that point towards anemia.

Sample type: Serum Whole Blood
Avg. sample processing time: 6 Business days

Biomarkers

Basophil Count The number of basophils, a type of white blood cell involved in allergic and inflammatory responses, in your blood.
Basophils (%) The percentage of your white blood cells that are basophils, a cell type involved in allergic and inflammatory responses.
Eosinophil Count The number of eosinophils, a white blood cell type involved in allergic reactions and parasite defense, in your blood.
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.
Iron Measures the iron circulating in your blood, used along with other markers (like ferritin and TIBC) to evaluate for iron deficiency or overload.
Lymphocyte Count The number of lymphocytes, white blood cells central to your immune response (including T-cells, B-cells, and NK cells), in your blood.
Lymphocytes (%) The percentage of your white blood cells that are lymphocytes, key immune cells including T-cells, B-cells, and NK cells.
MCH Mean Corpuscular Hemoglobin — the average amount of hemoglobin per red blood cell, used to help classify types of anemia.
MCHC Mean Corpuscular Hemoglobin Concentration — the average concentration of hemoglobin within your red blood cells, used to help classify types of anemia.
MCV Mean Corpuscular Volume — the average size of your red blood cells, a key value used to help determine the cause of anemia.
Monocyte Count The number of monocytes, white blood cells that help fight infection and clear damaged cells, in your blood.
Monocytes (%) The percentage of your white blood cells that are monocytes, cells that help fight infection and clear damaged tissue.
Neutrophil Count The number of neutrophils, the most abundant white blood cell type and a first-line defense against infection, in your blood.
Neutrophils (%) The percentage of your white blood cells that are neutrophils, a first-line defense against infection.
Platelets Cell fragments that help your blood clot. Counted to screen for bleeding or clotting risk and various blood disorders.
RBC Red blood cell count — the number of oxygen-carrying red blood cells in your blood, used to help diagnose anemia or polycythemia.
RDW Red Cell Distribution Width — measures how much your red blood cells vary in size, helpful for narrowing down the cause of anemia.
Reticulocyte Count The number of young red blood cells in your blood, reflecting how actively your bone marrow is producing new cells.
TIBC Total Iron-Binding Capacity — reflects how much transferrin (the iron-carrying protein) is available in your blood, used with iron and ferritin to evaluate iron status.
Transferrin Saturation The percentage of transferrin (your iron-carrying protein) that's currently occupied by iron — a key marker for detecting iron deficiency or overload.
UIBC Unsaturated Iron-Binding Capacity — reflects how much additional iron your blood's transferrin could still carry, used with iron and TIBC to assess iron status.
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.

Anemia Profile B

$83.00

This panel checks key markers to see if the patient has levels that point towards anemia.

Sample type: Serum Whole Blood
Avg. sample processing time: 6 Business days
Require fasting: No

Biomarkers

Basophil Count The number of basophils, a type of white blood cell involved in allergic and inflammatory responses, in your blood.

Eosinophils (%) The percentage of your white blood cells that are eosinophils, elevated with allergies, asthma, or parasitic infections.
Ferritin Reflects your body's stored iron levels. Low levels point to iron deficiency; high levels can indicate iron overload or, since it's also an inflammation marker, other conditions.
Folate Vitamin B9, needed for cell division, DNA synthesis, and red blood cell production. Low levels can cause a type of anemia and are important in pregnancy.
Hematocrit The percentage of your blood volume made up of red blood cells. Used to help diagnose anemia or polycythemia (excess red blood cells).
