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.
Parking in either the Green, Blue or Gray garage is $5 per day. This fee is waived if the visitor exits within 30 minutes. Long-term parking passes are available from the parking cashier and in the lobby gift shops.
