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.
Why It Is Done. A carbon monoxide blood test is used to detect poisoning from breathing carbon monoxide. You might have this test if you have been exposed to the gas or if you have unexplained symptoms, such as: Headache, dizziness, or vision problems.
