Essentially, yes. 'Coombs reagent' is a common synonym, specifically referring to the antiglobulin serum used in the Coombs test, invented by Robin Coombs.
No. Antiglobulins are antibodies produced in other species (like rabbits) against human immunoglobulins. They are manufactured reagents for laboratory diagnostics.
It is used to diagnose conditions like autoimmune hemolytic anemia, hemolytic disease of the newborn, and to perform crossmatching before blood transfusions.
The Direct Antiglobulin Test (DAT) detects antibodies already bound to a patient's red blood cells in vivo. The Indirect Antiglobulin Test (IAT) detects antibodies in a patient's serum that can bind to red blood cells in vitro.
An antibody that reacts with and binds to human or animal globulin, especially used to detect the presence of other antibodies or antigens in blood.

Mnemonic
Think: ANTIbody against GLOBULIN (a protein). It's an antibody that targets other antibodies (which are globulins).
Conceptual Metaphor
A DETECTOR or MAGNIFIER. Antiglobulin doesn't find the primary target itself; it 'flags' or 'highlights' the antibody that has already bound, making invisible reactions visible.
