Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...
Basophil granulocytes, adult, range 0.015-0.15 × 10 6: Basophils, adult, median 0.03 × 10 6: Lymphocytes, birth 2-11 × 10 6: Lymphocyte, pediatric 1.5-8.0 × 10 6: Lymphocyte, adult, range 1.5-4.0 × 10 6: Lymphocyte, adult, median 2.5 × 10 6: Monocytes, birth, range 0.4-3.1 × 10 6: Monocytes, birth, median 1.05 × 10 6: Monocytes ...
In COVID-19 B cell, natural killer cell, and total lymphocyte counts decline, but both CD4 + and CD8 + cells decline to a far greater extent. [12] Low CD4 + predicted greater likelihood of intensive care unit admission, and CD4 + cell count was the only parameter that predicted length of time for viral RNA clearance.
The main cellular components of the human body by count [6] Cell type % cell count: Erythrocytes (red blood cells) 84.0 Platelets: 4.9 Bone marrow cells 2.5 Vascular endothelial cells: 2.1 Lymphocytes: 1.5 Hepatocytes: 0.8 Neurons and glia: 0.6 Bronchial endothelial cells: 0.5 Epidermal cells: 0.5 Respiratory interstitial cells: 0.5 Adipocytes ...
Anemia can be confirmed by a blood test if the hemoglobin value is less than 13.5 gm/dl in men or less than 12.0 gm/dl in women. [39] Several countries have blood banks to fill the demand for transfusable blood. A person receiving a blood transfusion must have a blood type compatible with that of the donor. Sickle-cell anemia
Natural killer cells, also known as NK cells, are a type of cytotoxic lymphocyte critical to the innate immune system.They are a kind of large granular lymphocytes [1] [2] (LGL), and belong to the rapidly expanding family of known innate lymphoid cells (ILC) and represent 5–20% of all circulating lymphocytes in humans.

Lymphoma is definitively diagnosed by a lymph-node biopsy, meaning a partial or total excision of a lymph node examined under the microscope. [22] This examination reveals histopathological features that may indicate lymphoma. After lymphoma is diagnosed, a variety of tests may be carried out to look for specific features characteristic of ...
A normal platelet count is considered to be in the range of 150,000–450,000 per microlitre (μL) of blood for most healthy individuals. Hence one may be considered thrombocytopenic below that range, although the threshold for a diagnosis of ITP is not tied to any specific number. [2]
