Lymphocytopenia is the condition of having an abnormally low level of

lymphocytes in the blood. Lymphocytes are a white blood cell with important functions in the immune system. It is also called lymphopenia.[1] The opposite is lymphocytosis
, which refers to an excessive level of lymphocytes.

Lymphocytopenia may be present as part of a pancytopenia, when the total numbers of all types of blood cells are reduced.

Classification

In some cases, lymphocytopenia can be further classified according to which kind of lymphocytes are reduced. If all three kinds of lymphocytes are suppressed, then the term is used without further qualification.

Causes

The most common cause of temporary lymphocytopenia is a recent infection, such as the common cold.[citation needed]

Lymphocytopenia, but not idiopathic

iatrogenic
(caused by other medical treatments) conditions.

Lymphocytopenia is a frequent, temporary result from many types of

Hodgkin's disease,[8][9]
also cause lymphocytopenia.

Another cause is infection with

2009 flu pandemic and in 2016 for the Influenza-epidemic in Brazil.[11] The SARS disease caused lymphocytopenia.[12] Among patients with laboratory-confirmed COVID-19 in Wuhan China through January 29th, 2020, 83.2 percent had Lymphocytopenia at admission.[13]

Large doses of

whole body radiation, may cause lymphocytopenia.[14]

Diagnosis

Lymphocytopenia is diagnosed when the complete blood count shows a lymphocyte count lower than the age-appropriate reference interval (for example, below 1.0 x 10(9)/L in an adult).[citation needed]

Prognosis

Lymphocytopenia that is caused by infections tends to resolve once the infection has cleared. Patients with idiopathic CD4+ lymphocytopenia may have either abnormally low but stable CD4+ cell counts, or abnormally low and progressively falling CD4+ cell counts; the latter condition is terminal.[citation needed]

Other animals

Lymphocytopenia caused by

Lymphocyte T-Cell Immune Modulator.[15]
