The phrase "a second saliva" is not commonly used in written English and may sound awkward or unclear.
It could be used in a context discussing the production of saliva, perhaps in a scientific or medical discussion about saliva types or functions.
Example: "The study revealed that the body can produce a second saliva in response to certain stimuli, enhancing digestion."
Alternatives: "another type of saliva" or "a different saliva".

After DNA extraction, quantification and genotyping, 38 participants were recontacted to request a second saliva sample due to evidence of low yield (n = 15) or low initial genotyping rate (n = 23) when 3 or more out of 7 initial TaqMan® assays tested had failed.

Immediately after the MRI procedure, the child and parent were taken to a room to complete the remaining questions and take the second saliva sample.
Chewing gum significantly decreased production time for the second saliva samples by 3 6 min, and had very large effects on assay results, leading to lower IgA and higher T and E in men and women.
The second saliva sample was taken immediately after the particular intervention (learning while treadmill walking or sitting in a canvas chair) was finished.
The second saliva sample was taken between the letter and shape experiments and the last saliva sample was taken at the end of the experiment.
To evaluate discordance, 10% of the samples were genotyped in duplicate, as was the second saliva DNA sample collected for 18 participants.
