Lowest white blood count is it not necessary bad thing?

[RemakeRemarke]

Dh in hospital, chest pain which they think is OK but blood results say low white cells? Asking if he had cancer, diabetes etc?

He's a fit man, 43, runs etc

• low not lowest!

How is your husband now? I’ve had blood tests recently that show low white blood count and have to get repeated in a month.

Various reasons can cause this such as cancer treatment and autoimmune conditions. Early stages of leukaemia can start with low then high white blood cell counts. Most likely it will sort itself out, or nothing that is not treatable.

Has he had flu or anything like that?
