We investigate the thermal spectral densities for (pseudo)scalar and vector currents in the framework of the real time formalism when mass of two quarks are different. Such spectral densities are necessary for the phenomenological investigation of in-medium properties of hadrons. We use the quark propagator at finite temperature and calculate annihilation and scattering parts of spectral densities for above mentioned currents. The investigations show that the thermal contributions are significantly important. The obtained results at T 0 limit are in good consistency with the vacuum results.
