Diagnosis
When diagnosing lymphopenia, doctors primarily rely on the lymphocyte count, which indicates levels lower than the normal range for the patient’s age group. If a patient experiences frequent or uncommon infections, healthcare professionals usually suspect lymphopenia. In such cases, they may order a complete blood count with differential, along with a measurement of lymphocyte subpopulations. Additionally, some doctors may evaluate antibody production by testing immunoglobulin levels. It is important to note that even if the lymphopenia test results are normal, medical practitioners often conduct immunodeficiency tests if recurring infections are observed.
Screening and Prevention
Managing inherited lymphopenia is the primary focus as it cannot be prevented. On the other hand, acquired lymphopenia can be minimized by implementing certain lifestyle changes. One of the major risk factors for acquired lymphopenia is undernutrition. Therefore, maintaining a healthy diet is crucial in preventing a decrease in lymphocyte count.
