Conducting routine diagnostic assays and automated bench tests under supervision.

What is the primary scope of immunology and serology?

Identifies and measures antibodies, antigens, and immune system components responding to infectious diseases and autoimmune disorders.

Name two key diagnostic assays in immunology.

Viral panels (HIV, hepatitis) and antinuclear antibodies (ANA).

What type of tubes are used for collecting serum in immunology?

Serum separator tubes (gold/red-and-gray speckle) or plain red-top tubes.

What is the main focus of microbiology?
