The purpose of this study is to better understand the genetic factors related to the Chiari I malformation. In people with this abnormality, the lower part of the skull is smaller than normal.andidates for this study are: 1) Patients with Chiari I malformation who also have a family member with the abnormality or a family member with syringomyelia (a cyst in the spinal cord that is often associated with the Chiari I malformation).
A hemoglobin electrophoresis test is a blood test used to measure and identify the different types of hemoglobin in your bloodstream. Hemoglobin is the protein inside red blood cells that is responsible for transporting oxygen throughout your circulatory system to your tissues and organs.he types of hemoglobin include: 1  hemoglobin F: This type is found in growing fetuses and newborns. 2  hemoglobin A: This is the most common type of hemoglobin found in healthy children and adults. 3  hemoglobin C, D, E, M, and S: These (and many other, rarer variations) are types of abnormal hemoglobin.
About 90% of hemoglobin is hemoglobin A. (The A stands for adult type.) Although one chemical component accounts for 92% of hemoglobin A, approximately 8% of hemoglobin A is made up of minor components that are chemically slightly different. These minor components include hemoglobin A1c, A1b, A1a1, and A1a2. Hemoglobin A1c (HbA1c) is a minor component of hemoglobin to which glucose is bound. HbA1c also is referred to as glycosylated or glucosylated hemoglobin. Take care TIN.
