The only biology experiment on the Viking landers which gave a positive result was the Labeled Release experiment. It involved adding a nutrient solution to soil samples and monitoring for signs of metabolism, which were detected in three separate trials. The other experiments, including the Gas Chromatograph/Mass Spectrometer, Carbon Assimilation, and Gas Exchange, did not provide evidence of life on Mars.
