About Us
The DNA Diagnostic and Research Laboratory (DDRL) at KK Women’s and Children’s Hospital has been dedicated to providing high quality DNA-based testing for the molecular diagnosis, carrier testing and prenatal testing of genetic disorders, for over 10 years. Mutation detection methods used in the laboratory include automated capillary-based sequencing and genotyping, classic PCR, reverse dot blot hybridisation and Southern techniques. The laboratory currently provides DNA tests for over 10 genetic diseases, with continuing development of new tests and implementation of improved testing methodologies.

| Specimen Requirements for DNA Specimens |
Blood Specimens:
EDTA (purple) tubes; Adult: 5-10 mls, Child: 3-5 mls, Infant: 2-3 mls
Fetal Specimens:
We require that the referring centre contact us regarding prenatal cases prior to submitting any samples.
For the most accurate fetal results, analysis of family members is often required. For autosomal recessive conditions, blood specimens should be submitted from both parents and the affected sibling for molecular analysis. For autosomal dominant or X-linked conditions, the high risk parent and the affected relative should be studied. Some disorders may require analysis of additional family members for precise interpretation of fetal results.
Fetal specimens should be clearly labelled with the mother's full name, type of fetal sample (CVS or amnio), and if available, the fetal sex determined by cytogenetic data. Maternal blood is required for all prenatal tests to rule out contamination and sample switch. Clearly indicate if ordering cytogenetics or biochemical studies in addition to DNA
• Amniotic Fluid: 20mls
• Chorionic Villi: 10mg
