Hemoglobin (Hgb) Test Results

What is the Hgb test ? The hemoglobin ( Hgb ) test measures how much hemoglobin your crimson blood cells contain. Hgb is a protein produced by your cram kernel that ’ randomness stored in red blood cells. It helps bolshevik lineage cells transport oxygen from your lungs to your body through your arteries.

It besides transports carbon dioxide ( CO2 ) from around your body back to your lungs through your veins. Hgb is what makes red blood cells look red. abnormally high or low Hgb can cause symptoms like debilitation, dizziness, or shortness of breath. Your doctor may suggest an Hgb test if you ’ rhenium experiencing these symptoms. You may have an fundamental condition that needs to be diagnosed. Learn why you may need an Hgb test, what the typical ranges are for Hgb, and what can cause abnormal Hgb levels.

Why do I need the Hgb test?

The Hgb test uses a sample of your blood to determine hemoglobin levels. To take a sample, your healthcare supplier extracts lineage from a vein by pricking your finger or inserting a needle with an attached tube into the wrinkle of your sleeve. The sample is then stored in the tube to be analyzed late at a lab. The needle may cause brief discomfort, but the insertion normally lasts less than a moment. If you ’ rhenium sensible to getting rake draw or the sight of blood, have person come with you and let your provider know. The Hgb test may be ordered as separate of a complete rake count ( CBC ) test. A CBC screen besides measures other important components of your lineage, such as white blood cells and platelets. abnormal levels of any of these cells can indicate implicit in conditions or blood disorders. here are a few other reasons your doctor may order an Hgb test :

  • You have parents or other family members who have blood disorders, such as sickle cell anemia.
  • You have an infection.
  • You don’t have enough iron in your diet.
  • You’ve lost a lot of blood after surgery or a traumatic injury.
  • You’re pregnant.
  • You have a medical condition that can affect your Hgb levels.

You don ’ t need to fast for the Hgb test specifically. You may need to fast — avoiding food or liquids with calories for about 12 hours — if your doctor plans to test the chemistry of your lineage at the same clock time. You should drink enough of water, however .

What are the ranges for the test results?

Your historic period and gender both affect your Hgb levels. Typical healthy Hgb levels are as follows :CategoryHgb level, in grams per deciliter (g/dL)infants11–18young children11.5–16.5adult males13–16.5adult females (not pregnant)12–16adult females (pregnant)11–16 For men, Hgb levels below 13 g/dL are considered moo. For women, Hgb levels below 12 g/dL are considered broken if not pregnant. This doorway may change with certain conditions. It can besides deviate depending on the lab, so be sure to check your lab ’ mho reference range. For children these levels may besides vary due to age, specially in infants under 6 months old.

What are the causes of low hemoglobin?

low Hgb levels can be caused by any condition that affects your body ’ south ability to create red blood cells or conditions that lower red rake cells in your bloodstream. potential causes of low Hgb include :

  • lack of iron in your diet, which makes it harder for your bone marrow to produce Hgb
  • lack of folate or vitamin B-12, which can lead to your body producing fewer red blood cells than are needed
  • severe blood loss after surgery or a major injury
  • internal bleeding from stomach ulcers, stomach or colon cancer, or internal injuries
  • sickle cell anemia, a genetic condition that causes red blood cells to be abnormally sickle-shaped and able to carry less Hgb
  • hypothyroidism, which means that the thyroid gland doesn’t produce enough thyroid hormones
  • splenomegaly, or an enlarged spleen from infection, liver conditions, or cancer
  • bone marrow conditions, such as leukemia, that prevent your bone marrow from producing enough red blood cells
  • chronic kidney disease, in which your kidneys don’t function properly (resulting in a deficiency of erythropoietin, a hormone that stimulates red blood cell production in your bone marrow)

early causes can include :

  • donating blood too often
  • heavy bleeding during your period
  • alcohol misuse
  • chronic health problems such as autoimmune diseases or cancer

What are the symptoms of high hemoglobin?

high Hgb is known as polycythemia. This means you have excessively many red blood cells. Polycythemia vera is a cancer of the blood in which your cram marrow overproduces red lineage cells. With polycythemia, a blood trial besides shows that you have a high crimson rake cell count and high hematocrit. Common symptoms of high Hgb levels include :

  • itchiness
  • headache
  • dizziness
  • getting easily bruised or bleeding
  • sweating more than usual
  • painful joint swelling
  • abnormal weight loss
  • a yellow tint to the eyes and skin (jaundice)
  • feeling exhausted
  • a purple or reddish tint to the skin

What are the causes of high hemoglobin?

gamey Hgb may result from your body needing to store more Hgb in crimson blood cells due to your environment, a condition that affects your heart or lung function, or life style choices. possible causes of high Hgb levels include :

  • living at high altitudes where there’s not as much oxygen in the air, such as in the mountains
  • smoking tobacco products, including cigarettes or cigars
  • chronic obstructive pulmonary disease (COPD), a condition that inflames the lungs and blocks air from getting into your lungs
  • heart or lung diseases that affect your ability to breathe, your lungs’ ability to pass oxygen into your bloodstream, or your heart’s ability to pump normally
  • taking erythropoietin unnecessarily, such as to enhance high-level physical performance

other causes include :

  • being severely dehydrated
  • heart failure
  • cancer of the liver or kidneys

The takeaway

Your doctor may recommend a Hgb quiz if you have symptoms of abnormal Hgb levels or if you ’ re pregnant.

The earlier you notice the symptoms of abnormal Hgb levels and have the cause diagnosed, the more likely you are to have successful discussion. See your doctor if you ’ rhenium experiencing any symptoms of high or low Hgb. If you have a family history of rake disorders or conditions that can affect bone marrow or red rake cell product, you ’ ll likely need regular Hgb tests along with a CBC to monitor how these health problems may be affecting your blood cells .
