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.
There are 3,000 parking meters in the Historic District with time limits ranging from 30 minutes to 10 hours. The cost per hour varies with locations and ranges from $.30 to $1.00 per hour. Free parking at meters on Saturday and Sunday.
