FAQ

Frequently Asked Questions

No. A leukoblast is a normal, immature stage of a white blood cell. However, in cancers like leukaemia, these cells can become malignant and proliferate abnormally.

Typically, no. Leukoblasts are usually found in the bone marrow. Their presence in peripheral blood is abnormal and can be a sign of disease, such as leukaemia.

A lymphocyte is a specific type of mature white blood cell. A leukoblast is an immature cell that could develop into a lymphocyte or another type of white cell like a granulocyte.

It is a precise term from a highly specialised scientific field (haematology). In everyday language and even general medicine, broader terms like 'blast cells' or 'immature white cells' are more commonly used.
