The present disclosure provides a gate driving circuit, a method for detecting the gate driving circuit, an array substrate and a display apparatus. The gate driving circuit comprises a plurality of cascaded gate driving units, access units, a first signal line and a second signal line. Each access unit is connected to its corresponding gate driving unit and the gate driving unit at the next stage to its corresponding gate driving unit. The access unit corresponding to the gate driving unit at each odd stage is connected to the first signal line such that the first signal line detects an output signal from that gate driving unit via the access unit, and the access unit corresponding to the gate driving unit at each even stage is connected to the second signal line such that the second signal line detects an output signal from that gate driving unit via the access unit.
