Which laboratory test is commonly used to detect the presence of antibodies in a patient's serum?

Step 1: Understand that antibodies are proteins made by the immune system to fight infections.
Step 2: Know that doctors can check for these antibodies in a patient's blood, specifically in a liquid part called serum.
Step 3: Learn that a common laboratory test used for this purpose is called the Enzyme-linked immunosorbent assay, or ELISA for short.
Step 4: Recognize that ELISA works by using specific substances that react with the antibodies, allowing the lab to see if they are present.
