What it measures
Lymphocytes are white blood cells that fight viruses and remember germs you’ve met before, which is how vaccines protect you. This is a count of them in your blood.
Why it matters for women
Women’s immune systems tend to react more strongly, which may be one reason autoimmune conditions, where the body attacks itself by mistake, are more common in women. Some of these, like lupus, can lower your lymphocyte count. A short-term change during or after a cold or flu can be common.
You might check it if…
- you’ve had a viral illness that’s slow to clear
- you get infections often
- a doctor mentioned lupus or another autoimmune condition
- you take steroids or medicines that calm the immune system
What your result may mean
High Absolute Lymphocytes: what it may mean
A high absolute lymphocyte count (lymphocytosis) may reflect a viral infection such as mono or, less frequently, a lymphoproliferative disorder, where the body can make too many lymphocytes, such as chronic lymphocytic leukemia. Whooping cough, smoking, stress on the body and having your spleen removed can raise it too. A short rise during or after a cold or flu can be common and may settle as you recover. Swollen glands, a sore throat or tiredness can come with it, or there may be no symptoms.
Low Absolute Lymphocytes: what it may mean
A low absolute lymphocyte count (lymphopenia) can result from a sudden illness, steroid medicines or immune suppression, and it can raise your risk of infection. Autoimmune conditions can lower it as well, and lupus, which mostly affects women, may be one example. Cancer treatment, HIV and poor nutrition can also play a part. A short dip during a cold or flu can be common and may pass. Repeat infections can be a clue, while some people may feel fine.
