Blood is extremely dangerous when carried to the blood via the lungs by inhalation, because carbon monoxide irreversibly binds to hemoglobin to form carboxyhemoglobin, so that less hemoglobin is free to bind oxygen, and fewer oxygen molecules can be transported throughout the blood. This can cause suffocation insidiously. A fire burning in an enclosed room with poor ventilation presents a very dangerous hazard, since it can create a build-up of carbon monoxide in the air. Some carbon monoxide binds to hemoglobin when smoking tobacco. Blood for transfusion is obtained from human donors by blood donation and stored in a blood bank.
Glycated hemoglobin to IFCC methods HPLC-CE and HPLC-MS. A new unit (mmol/mol) is used as part of this standardization. The standardized test does not test for iodine levels in the blood. Hypothyroidism or iodine supplementation are known sources that artificially raise the A1c number. HbA1c is not generally used in the treatment of cats and dogs with diabetes; fructosamine is favoured instead. HbA1c has not been found useful in these animals. Glycated hemoglobin Glycated hemoglobin (hemoglobin A1c, HbA1c, A1C, or less commonly HgbA1c, haemoglobin A1c, HbA, Hb1c, etc.) is a form of hemoglobin that is bound to glucose. It is formed in
