Class 4 is the highest and most dangerous class of laser, including all lasers that exceed the Class 3B AEL. By definition, a class 4 laser can burn the skin, or cause devastating and permanent eye damage as a result of direct, diffuse or indirect beam viewing.
NeulastaÂ® is a prescription medication used to help reduce the chance of infection due to a low white blood cell count, in people with certain types of cancer (non-myeloid), who receive anti-cancer medicines (chemotherapy) that can cause fever and low blood cell count.
My white count bounced back to normal in a few days with Neulasta; the platelets in two weeks with red root tonic, but the hemoglobin took 4 months to get up to 11. I've been borderline anemic all my life and probably didn't have much in the way of red blood cell reserves.
