Overview
The primary purpose of DNA extraction from saliva is to isolate genetic material for subsequent analysis. This test is often the first step in various genetic evaluations, including: identifying genetic markers associated with hereditary diseases, confirming biological relationships in paternity cases, tracing ancestral origins, and guiding personalized medicine based on genetic variations. By extracting DNA from saliva, we enable accurate and comprehensive genetic testing without the need for invasive procedures.

Test Parameters & Specifications
Sample Stability
- Sample with visible food particles
- Insufficient volume (<1 mL)
- Sample leaking or not properly sealed
- Sample contaminated with blood or other fluids
- Sample not labeled correctly
Understanding Your Results
DNA Yield ≥ 2 µg, Purity 1.8-2.0
High-quality DNA suitable for all downstream applications
DNA Yield < 2 µg, Purity < 1.8
Low yield or contamination; may require re-extraction or alternative sample
DNA Integrity: High molecular weight
Intact DNA, ideal for sequencing and long-range PCR
If you are considering genetic testing for medical reasons, it is advisable to consult a genetic counselor or healthcare provider to understand the implications of the results and to guide appropriate testing.
Limitations
- ⚠Saliva may contain lower DNA yield compared to blood in some individuals
- ⚠Not suitable for certain tests requiring whole blood (e.g., hematological disorders)
- ⚠Contamination can lead to degraded DNA and failed analysis
- ⚠Results are dependent on sample quality and proper collection
Risks & Considerations
- ●No significant risks associated with saliva collection
- ●Minor discomfort from spitting
- ●Potential for sample contamination if instructions not followed
Interfering Factors
- ●Contamination with food particles or beverages
- ●Presence of tobacco or smoking residues
- ●Improper storage of saliva sample
- ●Insufficient saliva volume
- ●Use of mouthwash or dental products before collection
