If you have a hemoglobin variant, such as sickle cell hemoglobin (hemoglobin S), you will have a decreased amount of hemoglobin A. This may limit the usefulness of the A1c test in monitoring your diabetes. If you have anemia, hemolysis, or heavy bleeding, your test results may be falsely low.
Who was the president that believed that a US-controlled canal across Central America was a vital strategic interest to America and so was largely responsible for construction of the Panama Canal? Theodore Roosevelt
The Hay-Bunau-Varilla Treaty allowed the U.S. to build the Panama Canal and provided for perpetual control of a zone five-miles wide on either side of the canal. Although the French had attempted construction of a canal in the 1880s, the Panama Canal was successfully built from 1904 to 1914.
