Minor hair loss is a normal part of the hair-growing cycle. Each hair lives about 4.5 years, falls out and is replaced in about six months. If your hair is falling out in clumps, certain lifestyle practices or changes may be to blame, but consult a physician to rule out underlying medical conditions.
Blood draw: Removal of blood, usually by venipuncture (phlebotomy, venous blood sampling). Common term for blood sampling for laboratory analysis.
What It Is. Blood testing by a laboratory. The basic Medicare rule regarding blood tests is that Medicare covers the drawing of blood and laboratory testing, reasonably ordered by a physician or other appropriate practitioner, to diagnose or monitor a particular disease or condition.
