Monitor Detects White Blood Cell Levels

One of the major side effects of chemotherapy is a sharp drop in white blood cells, which leaves patients vulnerable to dangerous infections. Chemotherapy patients usually receive a dose every 21 days. After each dose, their white blood cell levels fall and then gradually climb again. Doctors usually only test patients’ blood just before a new dose, so they have no way of knowing if white blood cell levels drop to dangerous levels following a treatment.
