AST (SGOT) is primarily found in the muscles, liver, and heart. As such, these enzymes will be within the normal range on a blood test. However, if there is any injury or damage to your muscles, liver, or heart, these enzymes spill into the bloodstream and will be reflected in the blood report as being elevated.
There's also a 24/7 public parking garage across the street from Mt. Royal Station at The Fitzgerald. While not as close as the Penn Station garage, it has the same $12 max daily rate & it's monthly rate is only $130.
Most of the garages are situated a fair distance from the stadium, with the exception of the Fountain Square South Garage, which offers rates starting at $1 for the first hour and $5 for up to eight hours of evening parking. More information on rates and policies is here.
