We study dilepton production from a quark-gluon plasma of given energy density at finite quark chemical potential \ensuremath{\mu} and find that the dilepton production rate is a strongly decreasing function of \ensuremath{\mu}. Therefore, the signal to background ratio of dileptons from a plasma created in a heavy-ion collision may decrease significantly.
