Serum hemoglobin is a test that measures the level of free hemoglobin in the liquid part of the blood (the serum). Free hemoglobin is the hemoglobin outside of the red blood cells. Most of the hemoglobin is found inside the red blood cells, not in the serum.
Alternative NamesBlood hemoglobin; Serum hemoglobin
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 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 performedHemoglobin (Hb) (the main component of red blood cells) is a protein that carries oxygen away from the lungs to the body tissues. This test is done to diagnose or monitor the severity of various kinds of hemolytic anemia -- a low red blood cell count caused by the abnormal breakdown of red blood cells.
Normal Values- Females 12.3-15.3 g/dL
- Males 14.0-17.5 g/dL
Note: g/dL = grams per deciliter
What abnormal results meanElevated levels may indicate:
- Drug-induced immune hemolytic anemia
- G6PD deficiency
- Hemoglobin C disease
- Hereditary spherocytosis
- Idiopathic autoimmune hemolytic anemia
- Paroxysmal cold hemoglobinuria (PCH)
- Paroxysmal nocturnal hemoglobinuria (PNH)
- Sickle cell anemia
- Thalassemia
- Transfusion reaction
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:
- Excessive bleeding
- Fainting or feeling light-headed
- Hematoma (blood accumulating under the skin)
- Infection (a slight risk any time the skin is broken)

Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.
The examples above show the common measurements for results for these tests. Some laboratories use different measurements or may test different specimens.

What does the red top tube contain plasma or serum?
serum
What does the sst top tube contain plasma or serum after processing?
serum
Is serum glucose 123 to high?
serum glucose 123 to high?
Serum seperator tube?
Serum separating tube also referred as SST is used in medical clinical chemistry that requires the blood serum.
How do you obtain blood serum?
Serum is obtained from a SSt tube, which is allowed to clot and is then centrifuged
Why low serum iron and iron saturation but normal hemoglobin and hematocrit?
waht is the sideeffects of low iron serum....
A low serum concentration of hemoglobin is most often associated with a deficiency of?
Iron.
Serum is described as hemolyzed in the presence of increased?
Lipids in a nonfasting patient
When you hemoglobin is leaking what color the serum is?
Hemolysis results when red blood cells are destroyed or damaged during collection and the hemoglobin and other intracellular components leak into the fluid portion of the specimen. This yields pink to red serum or plasma depending on the severity degree of hemolysis.
How are iron levels in the body measured?
Iron levels in the body are measured by both hemoglobin and serum ferritin blood tests.
What color does your skin turn when hemoglobin is low?
It highly depend on the circumstance. Some bacteria will destroy the hemoglobin, and thus the hemolyzed blood appears transparents, whereas other process will only destroy the hemoglobin wall and thus liberating the hemoglobin, which is then pale cherry roughly in color.
Does blood have protein?
yes there is protein in the blood in the form of albumin serum. albumin serum is protein which can symbolise general health of a person. Low albumin levels indicate infections, malignancies, tumours. high albumin serum indicate dehydration
Plasma minus clotting proteins?
Serum
Does low iron affect weight?
Having enough iron may help you lose weight as opposed to having low iron serum levels. Iron is essential to your body for making hemoglobin. Hemoglobin is a transporter of oxygen in your body. So, the more iron, the more hemoglobin which will increase oxygen transport and thus the breakdown of complex sugars, which are carbohydrates. So, yes it can help boost your metabolism.
Will blood be red without hemoglobin?
No. The primary cause of the red color we associate with arterial blood is caused by the color of hemoglobin in its oxygen bound state. If I may speculate as to what color blood would be without hemoglobin, I would guess probably a rather light brown. I am basing that speculation on the the fact that serum (the cell-free, liquid component of blood) is a light brown color and that most cells are white-grey in color.
What is lacking antibodies of a specific type in serum?
Serum is serum
Blood plasma minus fibrinogen is?
Serum Serum
