Overview
The primary purpose of DNA extraction from milk is to obtain pure, high-molecular-weight DNA for genetic analysis. This procedure is essential for paternity testing, where DNA from the child (obtained from milk) is compared with that of the alleged father. In forensic science, DNA extracted from milk found at crime scenes can help identify individuals. Additionally, it is used in genetic research to study hereditary conditions and in clinical diagnostics to detect mutations associated with disorders like lactose intolerance and galactosemia. The extracted DNA serves as a template for various molecular techniques, including PCR, sequencing, and genotyping, enabling accurate and reliable results.

Doctor's Notes
Reviewed by Dr Pasupathy Arumugam — MBBS, MD (Pathology) · Reg. No. 21521
"DNA extraction from milk is a reliable, non-invasive method for genetic analysis. It is particularly useful in pediatric cases where blood sampling is challenging. The extracted DNA can be used for paternity testing, forensic identification, and screening for genetic disorders like lactose intolerance."

Test Parameters & Specifications
Sample Stability
- Hemolyzed or clotted sample
- Insufficient volume (< 2 mL)
- Sample contaminated with foreign material
- Improperly labeled or unlabeled sample
- Sample stored beyond stability period
Understanding Your Results
High DNA yield with good purity
Sample is suitable for downstream applications
Low DNA yield
May require re-collection or concentration
DNA degradation
Sample was not handled properly; re-collection recommended
PCR inhibitors present
May affect amplification; additional purification needed
Consult a geneticist or healthcare provider if you require DNA testing for medical, legal, or research purposes. They can guide you on the appropriate test and interpretation of results.
Limitations
