What if Lymphocytes Results Are High?
High blood levels of lymphocytes often indicate infection or inflammation. Temporary increases in lymphocyte levels are common after:
- recent infection (especially viral)
- chronic medical conditions linked to inflammation, such as arthritis or autoimmune disorders
- severe medical illness such as trauma, or after spleen removal
- a reaction to a new medication
Additional blood tests and further clinical investigation are often used to help determine the cause.
Often, no immediate action is taken. Persistently elevated lymphocyte levels are commonly reviewed further to clarify the underlying reason.
What if Lymphocytes Results Are Low?
Lymphocytopenia is the term used for a lower than normal number of lymphocytes in the blood.
The most common causes of decreased lymphocyte levels include viral infections and nutrition, although many disorders can also be linked to lymphocytopenia.
This finding is commonly looked at alongside additional blood test results and may be reviewed further to clarify the cause.
Lymphocytopenia can be present without symptoms, and it can also be associated with feeling unwell.
