What lab values indicate Microcytic anemia?
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 MCV (less than 83 micron 3). Iron deficiency is the most common cause of microcytic anemia.
Which anemia is associated with splenomegaly?
Anemia with peripheral smear findings showing spherocytosis, sickle cells, hemoglobin SC, or elliptocytosis would indicate splenomegaly due to these disorders. Anemia with a high lactate dehydrogenase (LDH) or low haptoglobulin level and a high bilirubin level may indicate a hemolytic disorder or liver disease.
How do you diagnose Microcytic anemia?
Diagnosing microcytic anemia Microcytic anemias are often first spotted after your doctor has ordered a blood test known as a complete blood count (CBC) for another reason. If your CBC indicates that you have anemia, your doctor will order another test known as a peripheral blood smear.
What lab tests are altered by anemia?
Testing for anemia includes CBC with platelet count and automated differential. A CBC includes red blood cell (RBC) indices that can be used to further classify anemia, suggesting possible diagnoses and additional testing. A reticulocyte count is commonly ordered with a CBC to assess bone marrow response to anemia.
What is MCV lab?
What is an MCV blood test? MCV stands for mean corpuscular volume. There are three main types of corpuscles (blood cells) in your blood–red blood cells, white blood cells, and platelets. An MCV blood test measures the average size of your red blood cells, also known as erythrocytes.
Why does iron deficiency anemia cause splenomegaly?
IDA is correlated with the incidence of splenomegaly, and the incidence of splenomegaly significantly increases as the severity of IDA increases. This is considered to be caused by extramedullary hematopoiesis.
Why does anemia cause splenomegaly?
Splenomegaly is usually associated with increased workload (such as in hemolytic anemias), which suggests that it is a response to hyperfunction. It is therefore not surprising that splenomegaly is associated with any disease process that involves abnormal red blood cells being destroyed in the spleen.
Which of the following lab tests confirms a diagnosis of iron deficiency anemia when evaluating microcytic anemia?
Ferritin/Iron and Iron Binding Capacity SF and TIBC (which includes calculation of transferrin saturation) are the first-line tests to evaluate iron stores and can differentiate between IDA and other forms of microcytic anemia.
What is MCV in blood test?
MCV stands for mean corpuscular volume. There are three main types of corpuscles (blood cells) in your blood–red blood cells, white blood cells, and platelets. An MCV blood test measures the average size of your red blood cells, also known as erythrocytes.
What is Tibc blood test mean?
A total iron-binding capacity (TIBC) test measures the blood’s ability to attach itself to iron and transport it around the body. A transferrin test is similar. If you have iron deficiency (a lack of iron in your blood), your iron level will be low but your TIBC will be high.
How common is splenomegaly in iron deficiency anemia?
Splenomegaly may occur with severe, persistent, untreated iron deficiency anemia. This is uncommon in the United States and Europe. Hempel EV, Bollard ER.
How is severe microcytic anemia diagnosed?
In moderately severe microcytic anemia, the diagnosis of iron deficiency should only be made with a history of an iron poor diet (ages 6 to 36 months) or explained blood loss without a history and physical exam suggesting another cause.
Which tests are performed in the workup of splenomegaly?
If the patient is not ill, has no symptoms besides those due to splenomegaly, and has no risk factors for infection, the extent of testing is controversial but probably includes CBC, peripheral blood smear, liver tests, and abdominal CT.
What is iron deficiency hypochromic microcytic anemia?
Iron deficiency hypochromic microcytic anemia is caused due to disruption of iron supply in diet due to decreased iron content in the diet, pathology the small intestines like sprue and chronic diarrhea, gastrectomy, and deficiency of vitamin C in the diet.
