It is also abbreviated as “hgb”. Hemoglobin is the protein present in your red blood cells that carries oxygen from the lungs to the body tissues and returns carbon dioxide from the tissues to the lungs.
Like all proteins, hemoglobin is also made of amino acids but with polypeptide chains in which two alpha chains of 141 amino acid residues each and two beta chains of 146 amino acid residues each.
Hemoglobin is a protein in red blood cells that carries oxygen. A blood test can tell how much hemoglobin you have in your blood.

How the test is performedBlood is typically drawn from a vein, usually from the inside of the elbow or the back of the hand. The site is cleaned with germ-killing medicine (antiseptic). The health care provider wraps an elastic band around the upper arm to apply pressure to the area and make the vein swell with blood.
Next, the health care provider gently inserts a needle into the vein. The blood collects into an airtight vial or tube attached to the needle. The elastic band is removed from your arm.
Once the blood has been collected, the needle is removed, and the puncture site is covered to stop any bleeding.
In infants or young children, a sharp tool called a lancet may be used to puncture the skin and make it bleed. The blood collects into a small glass tube called a pipette, or onto a slide or test strip. A bandage may be placed over the area if there is any bleeding.
How to prepare for the testNo special preparation is necessary.
How the test will feelWhen the needle is inserted to draw blood, some people feel moderate pain, while others feel only a prick or stinging sensation. Afterward, there may be some throbbing.
Why the test is performedThe hemoglobin test is almost always done as part of acomplete blood count(CBC). Normal ValuesNormal results vary, but in general are:
Note: gm/dL = grams per deciliter
Note: Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.
What abnormal results meanLower-than-normal hemoglobin may be due to:
Higher-than-normal hemoglobin may be due to:
Additional conditions under which the test may be performed:
Veins and arteries vary in size from one patient to another and from one side of the body to the other. Obtaining a blood sample from some people may be more difficult than from others.
Other risks associated with having blood drawn are slight but may include:

hemoglobin F
The mineral element connected to hemoglobin is Iron.
Hemoglobin is the protein that, along with water, makes up a red blood cell. Hemoglobin is made from two substances, heme and globin. In order for hemoglobin synthesis to take place, two chains of globin must connect to one another. Without these chains, hemoglobin synthesis cannot happen.
Carbon monoxide bind easily to hemoglobin.
There is approximately 3.47 mg of iron in 1 gram of hemoglobin.
No, hemoglobin is a protein.
what is hemoglobin?
hemoglobin
This chemical is hemoglobin.
Hypochromia (as in hypochromic anemia) is the medical term meaning deficiency in hemoglobin.
Yes crocodiles do have a Hemoglobin.
No, hemoglobin is a protein.
It is called hemoglobin. Hemoglobin carries oxygen and iron to the tissues.
Well, the high concentration of hemoglobin is what gives our blood its red color. More specifically, the porphyrin functional group in the hemoglobin structure is what gives hemoglobin (and oxy-hemoglobin) its red hue.DO NOT LET ANYONE TELL YOU THAT HEMOGLOBIN IS RED BECAUSE OF THE IRON IN THE CENTER OF ITS STRUCTURE. THEY WOULD BE LYING TO YOU.
Hemoglobin carries oxygen to the cells. Hemoglobin is contained in red blood cells.
hemoglobin is the cause thats why your blood is red
Heme + globin is Hemoglobin.
