Low white blood cell count symptoms

Updated July 11, 2018

Fewer than 3,500 white blood cells per microliter of blood typically indicates a low count, although it varies among adults. Pay close attention to any symptoms you may be exhibiting, because a low white blood cell count can be a sign of a serious condition.


Various cancers, treatments for cancer (such as chemotherapy), medications, allergies, autoimmune diseases and viruses can lead to low white blood cell counts.


Those suffering from low white blood cell counts may experience such symptoms as fevers, infections (particularly frequent sinus and urinary tract infections) and the need for excess sleep.


Low white blood cell counts can make one susceptible to infections. As a result, take precautionary measures against germs by washing your hands regularly and wearing a protective mask.


Treatment for symptoms varies depending on the underlying cause of the condition. Antibiotics can help fight infections, while white blood cell transfusions simply aim to replenish the imbalance.


White blood cells are formed in bone marrow. A decrease in the cells can lead to problems in this region such as leukaemia (bone marrow cancer) and aplastic anaemia.
