A. AST (SGOT) and ALT (SGPT) are sensitive indicators of liver damage or injury from different types of diseases. But it must be emphasized that higher-than-normal levels of these liver enzymes should not be automatically equated with liver disease.
Difference Between Price Ceilings and Price Floor Both price ceilings and floors are forms of price controls. While a price ceiling dictates the maximum price of a good or service, a price floor refers to the lowest price for which a good or service may be sold.
Price Floors When a price floor is set, a certain minimum amount must be paid for a good or service. If the price floor is below a market price, no direct effect occurs. If the market price is lower than the price floor, then a surplus will be generated. Minimum wage laws are good examples of price floors. In many states, the U.S. minimum wage law has no effect, as market wage rates for low-skilled workers are above the U.S. minimum wage rate.
