What is a low blood count?
A low blood count means that you have fewer red or white blood cells or fewer platelets in your body than normal.
A low blood count is diagnosed using a test called a full blood count, where your blood levels are compared with the population average. This is performed in a lab and involves considering many factors. “Normal” levels differ between men and women, and also across ages. Your blood count can also vary due to pregnancy, your intake of caffeine, tobacco, and alcohol, your diet, and even the time that you have a blood sample taken.

As long as the underlying condition is treated, your blood count should return to normal
