Does urine hold DNA:- Deoxyribonucleic acid provides information about your health, growth, and aging.Urine does contain small amounts of DNA, but not nearly as much as blood or saliva. DNA also deteriorates more quickly in urine, making it difficult to extract and produce reliable test results.

Thus, DNA in urine lasts for 28 days. Note: Urine contains some DNA, but not nearly as much as blood or saliva. In addition, DNA degrades faster in urine, making it difficult to extract and produce reliable test results

how long does urine hold dna at room temperature

When urine is stored at -20°C, around 75% of the DNA degrades within 28 days, making a quantitative recovery difficult after this period . A temperature of -80°C improves recovery up to 28 days of storage but increases storage costs
