A falsely high A1C result can occur in people who are very low in iron; for example, those with iron-deficiency anemia. Iron Deficiency is a problem that affects almost 80% of the population around the world. The most common cause is anemia (most often due to low iron stores or a B12 or folate deficiency). Optimally, you’d have an A1c below 7% accompanied by a low blood sugar variance (high time-in-range). Iron deficiency anemia, a major public health problem in developing countries, is associated with higher HbA1c and higher fructosamine [3]. A good general guideline is: The higher your A1c, the more important it is to focus on getting it down. Hemoglobin A1c, often abbreviated HbA1c, is a form of hemoglobin (a blood pigment that carries oxygen) that is bound to glucose. A1C testing. In addition, iron replacement therapy leads to a drop in HbA1c in both diabetic and non-diabetic patients. High A1c as it can’t compared to the blood glucose levels. Inaccurate readings can also occur in people with kidney or liver disease. Like blood sugar levels, HbA1c levels are also affected by presence of variant haemoglobin, haemolytic anaemia, nutritional anaemias, uremia, pregnancy and acute blood loss. The higher the A1C the poorer your blood sugar control. Background: Iron deficiency anaemia is the most common form of anaemia in India.Haemoglobin A1c (HbA1c) is used in diabetic patients as an index to reflect glucose levels of the previous 3 months. The aim of this s … ; The normal range for level for hemoglobin A1c is less than 6%. high hemoglobin low protein in kidneys High sugar levels after breakfast HBa1C and 90 day average High hemoglobin levels during pregnancy and fetal risk average hba1c in uk amongst diagnosed diabetics Hello and some pregnancy/HBA1C advice please!! The thought is that high iron levels may cause damage to muscle tissue, thereby decreasing the body’s ability to move glucose from the blood into cells and also interfering with insulin production. The majority of individuals have just one type of hemoglobin, called hemoglobin A. The lower your A1c, the more important time-in-range becomes. The target A1c level for people with diabetes is usually less than 7%. Blood smear (also called a peripheral smear): In this test, a trained laboratorian looks under the microscope at a thin layer of blood on a slide treated with a special stain. I usually use iron-free vitamins, because iron can contribute to cardiac problems, and people with diabetes are at increased risk of that. Another study from 2004 showed similar results: About 33,000 healthy women with high iron stores followed for 10 years had a significant increase in the incidence of Type 2 diabetes. Kale is high in vitamin C, which might lower fasting blood sugar levels for people with type 2 diabetes. Consistent with these observations, iron replacement therapy lowers both HbA1c and fructosamine concentrations in diabetic and non-diabetic individuals [3-5]. RESEARCH DESIGN AND METHODS Prospective cohort study of 13,288 participants in the Atherosclerosis Risk in Communities Study. Both an increase of A1c hemoglobin -- due to the presence of high blood sugar -- or a decrease in total hemoglobin can make the A1c percentage higher. Iron is a mineral found mostly in red blood cells, also known as erythrocytes. If you are consuming a low protein diet or a poor protein diet, then the same thing happens. Hemoglobin is a protein in red blood cells that helps blood carry oxygen throughout the body. In turn, A1c test results may be falsely low. Low iron and Hemoglobin count Latest HbA1c - 5.6% Test strips, Blood Pressure and Diabetics. About Contact Editorial Policy Write For Us Follow Us Moreover, I have seen such reports from pregnant women, which is astounding, since optimizing blood glucose control is especially critical during pregnancy. Your red blood cell production increases to make up for chronically low blood oxygen levels due to poor heart or lung function. A1C test for diabetes diagnosis might lead to over or miss the diagnosis. Various problems will also cause high ferritin, like pancreatitis. What should be evaluated is time spent in range. This isn’t optimal for overall management. So, I wonder if that has anything to do with my higher A1c. If you have an uncommon form of hemoglobin (known as a hemoglobin variant), your A1C test result may be falsely high or falsely low. So less hemoglobin meas that percentage will be elevated. For example, according to a paper published in the Journal of General Internal Medicine, high levels of vitamin E can falsely elevate A1c levels. Cardio C-Reactive Protein “High Sensitive” CRP is a marker for inflammation. Clinical Practice Diabetes Care 2010 Apr; 33(4): 817-819. Certain types of anemia associated with decreased hemoglobin production or longer lifespan of red blood cells can elevate the proportion of hemoglobin present in the A1c form. This will result in high ferritin because the body stores and recycles the iron from myoglobin. The iron status of the patient must be consid … Effects of iron deficiency anemia on hemoglobin A1c in type 1 diabetes mellitus Pediatr Int. You've taken drugs or hormones, most commonly erythropoietin (EPO), that stimulate red blood cell production. These are the most common blood cells in the bloodstream. So when I read, as reported here, that low iron can make your A1c higher than it should be, I decided to try taking iron-containing multivitamins a couple of weeks before my next A1c. Low C-peptide test is diagnostic to type1 DM and type 3 C DM along with high blood sugar. It differs from a fasting glucose measurement in that fasting glucose is a snapshot of your blood glucose level at that one moment in time, when you first wake up in the morning before eating. Elevated Pancreatic enzymes is a marker of pancreatitis and thus diagnostic for type 3C DM along with other Diabetes tests . Uremic patients with blood urea nitrogen levels greater than about 85 mg/dL also develop significantly high levels of carbamylated hemoglobin, which interferes with some HbA1c assays. ... Hemoglobin A1C Reflects average blood sugar level for past 2-3 months by measuring the percentage of hemoglobin coated with sugar. Setting Goals for A1c Levels. Hemoglobin A1c (HbA1c, or sometimes just called an A1c) is a way to assess your average blood glucose levels. You're not likely to get a high hemoglobin count from EPO given to you for chronic kidney disease. I checked out my blood results and my iron level is barely above the low cutoff for normal. If someone has an A1C that is 6.2% and that is the only “look” at glucose control that is evaluated then a practitioner will be missing the variance in glucose which typically will include time spent too low (as well as too high). If your glucose levels have been high over recent weeks, your hemoglobin A1c test will be higher. If the case is severe, untreated, and/or prolonged, iron-deficiency anemia—a decrease in the quantity, size, and function of the red blood cells—can result, having several notable consequences. Your bone marrow produces too many red blood cells. Authors O Tarim 1 , A Küçükerdoğan, U Günay, O Eralp, I Ercan. What is more important: a low A1c or a high Time-in-Range? In general, low hemoglobin levels that need to be increased are caused by three circumstances: decreased red blood cell production (for example, altered bone marrow hemoglobin production, iron deficiency), increased red blood cell destruction (for example, liver disease), and by blood loss (for example, trauma from a gunshot or knife wound). While many people are familiar with iron deficiency, elevated iron levels in another thing all together. Blood also contains white cells, or leukocytes, which are part of the immune system, platelets involved in healing, and a variety of proteins. The amount of hemoglobin A1c will reflect the last several weeks of blood sugar levels, typically encompassing a period of 120 days. It also contains vitamin A, E, and K as well as folate, calcium, and iron. His very low-carbohydrate diet, A1C level of 5.3, and BMI of 19.8 kept his diabetes in remission without any drugs until his death. Previous studies suggest that iron deficiency anemia (IDA) affects the levels of HbA1c. Skeletal muscle mass decreases. ; The blood test for HbA1c level is routinely performed in people with type 1 and type 2 diabetes mellitus. Also, I read that people whose blood is low in iron can also test falsely high on their A1c. Why is Hemoglobin A1c important. Cardiac muscle tissue also decreases. If you have iron deficiency anemia, your A1C test results may be falsely high. Additionally, it has a low glycemic index, is high in fiber, and low in calories. The higher the hemoglobin A1c, the higher your risk of having complications related to diabetes. Reference: A1C for Screening and Diagnosis of Type 2 Diabetes in Routine. HgbA1C measures the percentage of Hgb that is glycosylated. This is especially true in people with anemia severe enough to need medications to stimulate erythropoietin. The major form of glycohemoglobin is hemoglobin A1c (HbA1c). History of the A1c test Hemoglobin A1c was first separated from other forms of hemoglobin by Huisman and Meyering in 1958 using a chromatographic column. If you have an uncommon form of hemoglobin (called a hemoglobin variant), your A1C test outcome may be incorrectly high or incorrectly low. Iron deficiency can occur for a number of reasons, from related medical conditions to blood loss to diet choices. The HbA1c fraction is abnormally elevated in chronic hyperglycemic diabetic patients and correlates positively with glycemic control. Most people have only one type of hemoglobin, called hemoglobin A. ; Blood HbA1c levels are reflective of how well diabetes is controlled. Any condition that shortens the life span of red blood cells such as hemolytic anemia or recent blood loss could lower A1c levels, while iron-deficiency anemia may increase A1c levels. Elders, black with an iron-deficient and genetic predisposition to high … A number of things can cause an elevated HgbA1C in the absence high blood sugars. Other causes of false A1C results include kidney failure or liver disease . may be low in anemia and high in excessive iron states and pregnancy. OBJECTIVE To identify predictors of low hemoglobin A1c (HbA1c) (<5.0%) and to investigate the association of low HbA1c with cause-specific mortality and risk of liver disease hospitalization. The hemoglobin count is an indirect measurement of the number of red blood cells in your body. Oh well, I'll know soon enough I guess. If you have iron-deficiency anemia, your A1C examination outcomes may be incorrectly high. -Severe anemia: Iron-deficiency anemia, a condition where you have low blood iron, leads to low hemoglobin levels. This may result in part from iron deficiency anemia, recent transfusions, or other effects of kidney disease on erythrocyte survival. This is because some evidence has suggested that those who have too much iron increase their risk of developing type 2 diabetes by up to 28%. What is a high hemoglobin count? Time and time again, I have seen stories of endocrinologists and general practitioners discouraging patients from an A1c level in the 4.5-5.5% range, with some even advocating for an A1c level of no lower than 6% or even 7%! 1999 Aug;41(4):357-62. doi: 10.1046/j.1442-200x.1999.01083.x. (Hemoglobin contains iron, which gives blood its red color.) In people with CKD, red blood cell production is lower for a number of reasons. If the MCV is low and iron-deficiency has been ruled out, the person may be a carrier of the thalassemia trait or have a hemoglobin variant that results in smaller than normal red blood cells (for example, Hb E). Glycated hemoglobin, measured by high-performance liquid chromatography, is the gold standard for monitoring blood glucose control in diabetes and can now also be used to diagnose diabetes when its results are ≥ 6.5%.
