Hypochromia

If adults have nucleated red blood cells (NRBCs) in their blood, it’s usually a sign of a life threatening condition. The optimal NRBC count is 0. Even very low NRBC counts could cause a doctor to order further testing. Nucleated red blood cells (NRBCs) are immature blood cells that have not completed development. They are not usually present at all in the circulating blood of adults. If you have NRBCs in your blood, it may indicate leukemia, certain blood disorders, or hypoxia (not enough oxygen in tissues). Newborn babies have some NRBCs, which disappear from their bodies within the This article will take a closer look at the NRBC blood test, including how to interpret results and what to expect after an irregular result. If your doctor suspects certain conditions, they may order an NRBC blood test to check for the presence of these cells. But these cells are only indicators. This means that if these cells are in your blood, the doctor would order further testing to determine the underlying cause. Some studies suggest that NRBCs may help guide doctors who treat intensive care (ICU) patients. One Another During blood cell production, the red blood cell has a nucleus for only a very short time before expelling it. This process Diseases of the blood can stress the bone marrow and cause it to release NRBCs into the blood. Why this happens is still unclear, although inflammation or hypoxia may be the root cause. What conditions are associated with NRBCs? NRBCs can indicate th...

Iron deficiency is the most common cause of anemia and usually results from blood loss; malabsorption, such as with celiac disease, is a much less common cause. Symptoms are usually nonspecific. Red blood cells tend to be microcytic and hypochromic, and iron stores are low, as shown by low serum ferritin and low serum iron levels with high serum total iron-binding capacity. If the diagnosis is made, occult blood loss should be suspected until proven otherwise. Treatment involves iron replacement and treatment of the cause of blood loss. Iron is absorbed in the duodenum and upper jejunum. Iron absorption is determined by its source and by what other substances are ingested with it. Iron absorption is best when food contains heme iron (meat). Dietary nonheme iron is usually in the ferric state (+3) and must be reduced to the ferrous state (+2) and released from food binders by gastric secretions. Nonheme iron absorption is reduced by other food items (eg, vegetable fiber phytates and polyphenols; tea tannates, including phosphoproteins; bran) and certain antibiotics (eg, tetracycline). Ascorbic acid is the only common food element known to increase nonheme iron absorption. The average American diet, which contains 6 mg of elemental iron/1000 kcal of food, is adequate for iron homeostasis. Of about 15 mg/day of dietary iron, adults absorb only 1 mg, which is the approximate amount lost daily by cell desquamation from the skin and intestine. In iron depletion, absorption incre...

Hypochromia treatment What is hypochromia Hypochromia means that the red blood cells have less color than normal when examined under a microscope. Hypochromia usually occurs when there is not enough of the pigment that carries oxygen (hemoglobin) in the red blood cells. Hypochromia is defined as low mean corpuscular hemoglobin concentration (MCHC) in the setting of normal hemoglobin (Hb) in the red blood cells If you or your child develops signs and symptoms that suggest anemia or iron deficiency anemia, see your doctor. Anemia and iron deficiency anemia isn’t something to self-diagnose or treat. So see your doctor for a diagnosis rather than taking iron supplements on your own. Overloading the body with iron can be dangerous because excess iron accumulation can damage your liver and cause other complications. Hypochromia causes The most common cause of hypochromia in the United States is not enough iron in the body (iron deficiency). If it is not treated, this can lead to a disorder called iron deficiency anemia. Hypochromia and microcytosis Microcytic anemia is defined as the presence of small, often hypochromic, red blood cells in a peripheral blood smear and is usually characterized by a low mean corpuscular volume (MCV) (less than 83 micron) Iron deficiency anemia is a common type of anemia — a condition in which blood lacks adequate healthy red blood cells. Red blood cells carry oxygen to the body’s tissues. As the name implies, iron deficiency anemia is due to insuf...

Thalassemia What every physician needs to know: The thalassemias are among the most common genetic diseases worldwide and are attributable to unbalanced production of the hemoglobin molecule, due to either insufficient production of the α- or β-globin chains. The remaining globin chains precipitate in erythroid precursors and in red blood cells, resulting in an anemia from either ineffective production of red blood cells, hemolysis of red blood cells, or a combination of these effects. In the case of β-thalassemia, which is due to defective production of the β-globin chain of hemoglobin, the free α-globin chains precipitate in erythroid precursors causing anemia primarily due to impaired production of red blood cells. In α-thalassemia, reduced production of α-globin results in tetramers of β-globin known as hemoglobin H (HbH) that can precipitate within mature red blood cells. This in turn results in an anemia from hemolysis and destruction of these red blood cells, as well as some ineffective production of such red blood cells. The thalassemias generally are transmitted as simple Mendelian genetic diseases. If one acquires a single mutation of the globin genes (a heterozygous state) from the parents, then one is a carrier for thalassemia (described as thalassemia trait). Carriers can have abnormal red blood cell indices indicated by a low mean corpuscular volume (MCV) and mean corpuscular hemoglobin (MCH), abnormalities on hemoglobin analyses, and a mild anemia, but are g...

What is poikilocytosis? Poikilocytosis is the medical term for having abnormally shaped red blood cells (RBCs) in your blood. Abnormally shaped blood cells are called poikilocytes. Normally, a person’s RBCs (also called erythrocytes) are disk-shaped with a flattened center on both sides. Poikilocytes may: • be flatter than normal • be elongated, crescent-shaped, or teardrop-shaped • have pointy projections • have other abnormal features RBCs carry oxygen and nutrients to your body’s tissues and organs. If your RBCs are irregularly shaped, they may not be able to carry enough oxygen. Poikilocytosis is usually caused by another medical condition, such as The main symptom of poikilocytosis is having a significant amount (greater than 10 percent) of abnormally-shaped RBCs. In general, the symptoms of poikilocytosis depend on the underlying condition. Poikilocytosis can also be considered a symptom of many other disorders. Common symptoms of other blood-related disorders, such as anemia, include: • fatigue • pale skin • weakness • shortness of breath These particular symptoms are a result of not enough oxygen being delivered to the body’s tissues and organs. Poikilocytosis is typically the result of another condition. Poikilocytosis conditions can be inherited or acquired. Inherited conditions are caused by a genetic mutation. Acquired conditions develop later in life. Inherited causes of poikilocytosis include: • • • pyruvate kinase deficiency • McLeod syndrome, a rare genetic...
