How would I know if my hair loss is just telogen effluvium or something else?

In brief: Telogen effluvium
Laboratory studies are of little use in the diagnosis of telogen effluvium if there is clear history of an inciting event.
Scalp biopsy is the most useful test to confirm the diagnosis, although this is seldom necessary if the history is characteristic and a gentle hair pull produces numerous telogen hairs. Telogen hairs are identified by a white bulb and the lack of a gelatinous hair sheath.
