Mean Corpuscular Hemoglobin (MCH) Normal Range: 26-34 pg (picograms/cell)

The mean corpuscular hemoglobin, or "mean cell hemoglobin" (MCH), is the average mass of hemoglobin per red blood cell in a sample of blood. It is reported as part of a standard complete blood count.

It is diminished inmicrocytic anemias and increasedin macrocytic anemias.

It is calculated by dividing the total mass of hemoglobin by the number of red blood cells in a volume of blood. MCH=Hgb/RBC reference: http://en.wikipedia.org/wiki/Mean_corpuscular_hemoglobin

---- Macrocytic Anemia

* Types of macrocytic anemias ** 1.1 Megaloblastic anemias (DNA replication disorders) ** 1.2 Red cell membrane disorders producing codocytes ** 1.3 Alcohol ** 1.4 Association with rapid red cell turnover and reticulocytosis * Especially common causes of macrocytic anemias are the so-called megaloblastic anemias, in which cells are larger because they cannot produce DNA quickly enough to divide at the right time as they grow, and thus grow too large before division. Causes for the DNA synthetic problem range from lack of certain vitamins needed to produce DNA (notablyfolate and B12), to poisons or inhibitors of DNA replication, such as some kinds of antiviral drugs and chemotherapeutic agents.

* Macrocytosis, sometimes without associated anemia, is often evident in persons with chronic alcoholism. Although the macrocytosis of Alcoholism may be secondary to poor nutrition with a resulting folate or vitamin B-12 deficiency, it is more often due to a direct toxicity of the alcohol on the marrow. The macrocytosis of alcoholism usually reverses only after months of abstinence from alcohol. The remainder of the article can be seen on the following page

MCHC is the average hemoglobin concentration in red blood cells. It is increased in a condition known as hereditary spherocytosis (red blood cells are spherical instead of the normal oval shape). It is also increased in hemolysis (break down of red blood cells). In addition, lipemia and cellular dehydration syndromes can lead to increase in MCHC.

mchc results aren't usually reported, it is mainly used as a guideline for analyser function, if MCHC is elevated it us a good indicator the analyser is in need of attention, i.e if it is averaging high. However if the result is true it is a good indicator of Cold agglutination taking place in the sample, if the mchc corrects after the sample has been warmed for >15minutes @37C this is clinically reportable, if the mchc does not correct and is only slightly elevated e.g 367 372 it can be a rare true case of hereditary spherocytosis. An elevated MCHC blood level on laboratory findings can also indicate a Vitamin B12 or folic acid deficiency.

A high MCH level in the blood can be due to a macrocytic anemia. This is typically an anemia caused by the inability of hemoglobin cells to divide properly before they get too big and are then inefficient at carrying the appropriate nutrients to the body. A Vitamin B12 deficiency, poisons, chemotherapy, alcoholism, and other chemicals that damage DNA which in turn doesn't make the blood components develop properly or split in time is also a factor in macrocytic anemia. In all these cases, the MCH will be elevated and an indicator of the physical disorder.

Lymphocyte Level: The average is 3,900-10,000. Lymphocytes are part of your immune system and are released if there is an infection that needs to be "fought" off. So therefore, if your count is higher than 10,000 you probably have some kind of infection that your body is fighting off. If it is excessively high (say the 100,000 range) it is possible that you may have leukemia (cancer of the white blood cells). I'm sure your doctor would have told you if it was extremely high - so most likely you just have an infection. MCH (Mean Corpuscular Hemoglobin) Level: The average is 32-36%. This measures the amount of hemoglobin in your blood (hemoglobin is what transports oxygen to your tissues). High levels are not a problem unless you have a certain genetic disorder which causes excessive amounts and too many red blood cells to be produced. You would already know if you had this problem. Most likely it is just the norm for you. Just to let you know, health care providers generally do not look at this number as any kind of indicator of anything - your hemoglobin and hematocrit are the numbers that are reviewed mostly when it comes to how your blood is functioning.

Mean Corpuscular Volume, it means the volume of your red blood cells is high, so big cells. Doens't have to say anything on its own.

What does it mean to have high MCH on bloodwork?

MCH in blood work refers to Mean Corpuscular Hemoglobin. This is the concentration of hemoglobin in blood cells. High MCH can mean macrocytic anemia, which results from a deficiency in vitamin B12 or folic acid.


What causes raised lymphocytes and enlarged lymph nodes in toddlers?

To add-my son is 18 months old, and has had enlarged lymph nodes in his neck since birth. They are so large you can see them from across the room. His doc ordered a CBC and initially it came back with a total WBC count of 12.47 and lymphocyte count of 8.48. He said the WBC should have been around 10 and the lymphocyte around 4. Then a month later his WBC was 16.15 and lymphocyte at 8.08. Now a week later, his WBC is back down to 12.5, but his lymphocyte count raised back to 8.78. The only other thing he said was off was his MCH (mean count hemoglobin??) at 25.3 which was a little low. All his other types of cells are normal, including his other WBC types. At first he said he was concerned with his number of lymphocytes being so high, and now he is saying it might just be an infection that is getting better. Is it normal for your WBC to go down but your lymphocyte number to increase? Everywhere I read about it your lymphocyte number should be within 20-40% of your total WBC count.

What does that mean if you MCH test is high?

That is not possible. There is something wrong with your results. Tell your MLT/MT to rerun your CBC/MCH test. Spherocytes can cause MCH/MCHC to go high, but it is impossible. Spherocyte is a small red blood cell that have no central pallor
