Yes, both THC and THCA will show up as positive on a drug test. It is impossible to fully decarboxylate the full THCA content of the weed you smoke or dabs you take into THC, so you likely are absorbing THCA as well; the same goes for some types of rosin- and/or hash-based gummies due to the lack of cannabinoid isolation, though due to required lab testing, it’s less likely.
