Depression is a complex multi-faceted disorder with symptoms that can have multiple causes such as psychological, behavioral, and genetics. Decide where to place the TST. Whole blood (5 mL) collected in a green-top (LiHep) tube (QuantiFERON-TB Gold and T-SPOT.TB blood tests), 1 mL whole blood collected in each of 3 special (Nil, Antigen and Mitogen) specimen containers (QuantiFERON-TB Gold In-Tube test). [2], While there are theories that animals can experience depression it is important to keep in mind that human brains are much more complex than rat brains.
