If you have a positive test result on a SARS-CoV-2 antibody test, it is possible that you have recently or previously had COVID-19. There is also a chance that the positive result is wrong, known as a false positive. False positive tests may occur:
• Because antibody tests may detect coronaviruses other than SARS-CoV-2, such as those that
cause the common cold.
Sure. But did the OP also recently have symptoms consistent with covid-19? Especially loss of smell and/or taste? If so i would assume the positive test result means a recent covid-19 infection.
