There are two types of patients with HPFH: either with one normal copy of the gene and one disease form or with two disease copies. Whereas normal adults have less than 1% of hemoglobin F, patients with only one disease gene have 5-30%. Patients with two disease copies can have hemoglobin F in up to 100% of red blood cells. [31]
Hemoglobin Portland II (ζ 2 β 2). In fetuses: Hemoglobin F (α 2 γ 2; In neonates (newborns inmmediately after birth): Hemoglobin A (adult hemoglobin) (α 2 β 2 ) – The most common with a normal amount over 95%; Hemoglobin A 2 (α 2 δ 2) – δ chain synthesis begins late in the third trimester and, in adults, it has a normal range of 1. ...
The normal hemoglobin types are Hemoglobin A (HbA), which makes up 95–98% of total hemoglobin in adults, Hemoglobin A2 (HbA2), which constitutes 2–3% of total hemoglobin in adults, and Hemoglobin F (HbF), which is the predominant hemoglobin in the fetus during pregnancy, and may persist in small amounts in adults.

Individuals with TEC have a median age of presentation of 18–26 months; however, the disorder may occur in infants younger than 6 months and in children as old as age 10 years. Because of the gradual onset of the anemia, children are often healthier than expected from their low hemoglobin levels. [citation needed]
The normal range for hemoglobin is 13.8 to 17.2 grams per deciliter (g/dL) for men and 12.1 to 15.1 g/dL for women. [6] Low hemoglobin indicates anemia but will be normal for LID. [5] Normal serum iron is between 60 and 170 micrograms per deciliter (μg/dL). [7] Normal total iron-binding capacity for both sexes is 240 to 450 μg/dL. [6]
There are two types of Alpha-thalassemia, named hemoglobin Bart hydrops fetalis syndrome (also known as Hb Bart syndrome) and HbH disease. [22] Anemia: D50-D64: 663: Anemia is a type of medical condition that results in a decrease in the number of red blood cells (RBCs) or less than the normal quantity of hemoglobin in the blood. [2] Anemia of ...
A hemoglobin test measures the amount of hemoglobin in your blood. If a hemoglobin tests shows that a person's levels are below normal, it means they have a low red blood cell count, which is known as anemia. If the test shows higher levels than normal, it means they have hemoglobinemia. [citation needed] The normal range for hemoglobin is:
