Recorded summary

A smartphone camera measures colour reactions in an oxytocin ELISA using an LED-linked optical unit. The reported results compare the image-derived measure with conventional ELISA.

Recorded limitations

The method uses immunoassay reagents and a prepared sample. It does not measure circulating oxytocin from an ordinary facial photograph.
