In addition, the Society decided to discuss openly procedures that could be risky to sufferers of low back pain, including recommendations on surgery and other invasive therapies.

Alternative Names Clinical hemoglobin C Causes, incidence, and risk factors Hemoglobin C is an abnormal type of hemoglobin, the protein in red blood cells that carries oxygen. It is a type of hemoglobinopathy . The disease is caused by problem with a gene called beta globin. The disease most often occurs in African Americans. You are more likely to have hemoglobin C disease if someone in your family has had it.
Alternative Names Methemoglobin; Carboxyhemoglobin; Sulfhemoglobin Normal Values The following values represent the percentage of hemoglobin derivatives based on total hemoglobin: Carboxyhemoglobin: less than 3% (but may be as high as 15% in smokers) Methemoglobin: less than 3% Sulfhemoglobin: undetectable What abnormal results mean High levels of hemoglobin derivatives can lead to significant health problems. The altered forms of hemoglobin do not allow oxygen to be moved properly through the body. This can lead to tissue death. The following values, except sulfhemoglobin, represent the percentage of hemoglobin derivatives based on total hemoglobin: Carboxyhemoglobin: 10 - 20% symptoms of carbon monoxide poisoning begin to appear 30% severe carbon monoxide poisoning present 50-80% results in deadly carbon monoxide poisoning Methemoglobin: 10-25% results in cyanosis 35-40% results in shortness of breath and headache Over 60% results in lethargy and stupor Over 70% results in death Sulfhemoglobin: Values ...
