Definition

1. Noun:
   • A type of white blood cell: A lymph cell is an agranulocytic leukocyte. This means it is a white blood cell that lacks visible granules in its cytoplasm when viewed under a microscope.
   • Normal proportion and function: It normally constitutes about one-quarter (25%) of the total white blood cell count in a healthy individual. Its primary role is in the body's immune response.
   • Response to infection: The number of lymph cells increases in the presence of an infection as part of the body's defense mechanism.

Usage Examples

• Noun:
  • The laboratory test showed an elevated count of lymph cells, indicating a possible viral infection.
  • Lymph cells are crucial for the adaptive immune system, producing antibodies to fight pathogens.

Advanced Usage

• In medical diagnostics: The term is used to describe a specific finding in a complete blood count (CBC) test.
  • A differential white blood cell count measures the percentage of lymph cells.
• In immunological contexts: Often discussed in relation to specific types like T cells and B cells, which are categories of lymphocytes (a synonym for lymph cell).
  • The research focused on how specific lymph cells develop memory after an infection.

Variants and Related Words

• Lymphocyte (n): The more common and precise scientific synonym for "lymph cell."
  • T lymphocytes and B lymphocytes are the two main classes.
• Lymphocytic (adj): Relating to or involving lymphocytes.
  • The patient was diagnosed with a lymphocytic disorder.

Synonyms

• Lymphocyte: The direct and most frequently used synonym in medical and scientific English.
• Agranulocytic leukocyte: A more technical, descriptive synonym highlighting its classification among white blood cells.

Related Phrases

• Lymph cell count: A phrase referring to the measurement of these cells in a blood sample.
  • The doctor ordered a test to check the lymph cell count.
• Lymph cell production: Refers to the generation of these cells, primarily in the bone marrow and lymphoid tissues.
  • Chemotherapy can sometimes suppress lymph cell production.

Notes on Meaning

• The term "lymph cell" is functionally equivalent to "lymphocyte." "Lymphocyte" is the standard term in modern medical and biological texts, while "lymph cell" is a more descriptive term that clearly indicates its identity as a cell and its association with the lymphatic system.

Noun

1. an agranulocytic leukocyte that normally makes up a quarter of the white blood cell count but increases in the presence of infection
