Home pregnancy tests are a qualitative test and measure whether or not hCG -- the pregnancy hormone human chorionic gonadotropin -- is present in your urine, explains Stephen Rechner, M.D., the Division Chief of General Obstetrics and Gynecology at Spectrum Health in Grand Rapids.
After breathing in carbon monoxide, it enters your bloodstream and mixes with haemoglobin (the part of red blood cells that carry oxygen around your body), to form carboxyhaemoglobin. When this happens, the blood is no longer able to carry oxygen, and this lack of oxygen causes the bodyâs cells and tissue to die.
Low carbon monoxide levels in the blood stream (COHb) and cellular tissues are normal and necessary for proper cellular functioning. However there is not uniform agreement as to what normal levels in the blood stream are within different environments. Any carbon monoxide levels above normal is considered dangerous.
