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
On this day in 1977, President Jimmy Carter signs a treaty that will give Panama control over the Panama Canal beginning in the year 2000. The treaty ended an agreement signed in 1904 between then-President Theodore Roosevelt and Panama, which gave the U.S. the right to build the canal and a renewable lease to control five miles of land along either side of it.
