Basophils are a type of white blood cell. Although they’re produced in the bone marrow, they’re found in many tissues throughout your body. They’re part of your immune system and play a role in its proper function.
Basophils count is checked, if your immune system is not functioning properly. Sometimes basophils level may get low due to a severe allergic reaction.
The normal range for basophils is 0 to 300 per microliter of blood.
