Required Forms:
A completed requisition form, billing form, and consent form must be included with the sample. All samples must also be sent with patient clinical information and a copy (front and back) of their insurance card
Billing Items:
All samples must include patient clinical information relevant to the testing being ordered. This information helps us to work with the patient's insurance provider when securing coverage. We also request a copy (front and back) of their insurance card if the patient is going through private insurance.
For our next-generation sequencing testing panels, we are able to accept:
- Direct chorionic villi: 15-20mg
- 2 T-25 flasks of confluent fetal cells
- Extracted DNA: 3 micrograms in a minimum of 50 uL
Maternal cell contamination studies are also required prior to all next-generation sequencing tests; therefore a maternal blood sample is also required.
For samples sent for prenatal microarray, we are able to accept:
- Direct chorionic villi: 15-20mg
- 2 T-25 flasks of confluent fetal cells
Microarray result quality is adversely affected by some DNA extraction methods. To assure quality, we recommend sending direct chorionic villi (15-20 mg) or at least two cultured flasks of confluent fetal cells.
Maternal cell contamination studies are also required prior to array testing; therefore a maternal blood sample is also required.
Unfortunately, we are unable to perform testing on direct amniotic fluid samples at this time, due to low concentration of DNA present in these samples.
Additional specimen must be held for back-up culture at another facility.
Please note: If the sample volume is less than requested, tissue culture will be required. This will delay the processing of genetic testing and no guarantees can be made if the sample fails to grow in culture. We will notify the referring physician/counselor/laboratory if the sample is inadequate.
