levels of CK-MB to assess heart disease, insulin to assess hypoglycemia, prostate-specific antigen to detect prostate cancer, and some are also used for the detection and/or quantitative measurement of some pharmaceutical compounds (see Enzyme multiplied immunoassay technique for more details). Sports anti-doping analysis Immunoassays are used in sports anti-doping laboratories to test athletes' blood samples for prohibited recombinant human growth hormone (rhGH, rGH, hGH, GH). Research Photoacoustic Immunoassay The photoacoustic immunoassay measures low-frequency acoustic signals generated by metal nanoparticle tags. Illuminated by a modulated light at a plasmon resonance wavelength, the nanoparticles generate strong acoustic signal, which can be measured using a microphone. The photoacoustic immunoassay can be applied to lateral flow tests, which use colloidal nanoparticles.
