Overview
The primary purpose of DNA extraction from blood is to isolate high-quality genomic DNA for genetic testing. This includes diagnosing inherited disorders, identifying mutations associated with diseases, determining paternity, and supporting personalized medicine. The extracted DNA can be used for various tests such as carrier screening, prenatal diagnosis, and oncology panels. By providing pure DNA, we enable accurate and reproducible results in downstream analyses, which are crucial for clinical decision-making.

How to Prepare
- Use EDTA lavender-top tube for collection
- Mix the blood gently by inverting the tube 8-10 times to prevent clotting
- Label the tube with patient ID and date
- Transport the sample to the laboratory at 2-8°C if not processed immediately

Test Parameters & Specifications
Sample Stability
- Clotted sample
- Hemolyzed sample
- Incorrect tube (e.g., heparin or citrate)
- Sample not labeled properly
- Sample received after 48 hours without refrigeration
Understanding Your Results
Adequate for most molecular tests
High purity, free from protein contamination
Intact DNA, suitable for long-range PCR and sequencing
Consult your doctor if you have symptoms suggestive of a genetic disorder, or if you are planning a family and have a history of inherited conditions. Genetic counseling is recommended before and after testing.
Limitations
- ⚠DNA extraction alone does not provide diagnostic results; further testing is required
- ⚠Low DNA yield may occur in patients with low white blood cell counts
- ⚠Sample quality may be compromised if not stored properly
- ⚠Results are dependent on the quality of the blood sample
Risks & Considerations
- ●Minimal risk of bruising at the puncture site
- ●Rare risk of infection
- ●Dizziness or fainting during blood draw
Interfering Factors
- ●Hemolyzed blood samples may reduce DNA yield
- ●Clotted samples due to improper mixing with EDTA
- ●Contamination with nucleases causing degradation
- ●Insufficient sample volume
- ●Delay in processing leading to cell lysis
