Frequently Asked Questions
What is the difference between qPCR and Array CGH testing?Many of our clients have confusion about the difference between qPCR and Array CGH for testing deletions and duplications in genes. We recommend running deletion and duplication testing through qPCR when mutations are known. We use TaqMan qPCR for specific mutation analysis. Array CGH is useful for analyzing deletions and duplications of many genes without needing to know a specific known mutation first, and it is a much more comprehensive test. The entire coding regions and exon/intron boundaries are covered by array (the density of probes varies depending upon sequence homology of the tested regions; some regions may not have coverage due to the presence of pseudogenes). Array CGH is priced at $650 and qPCR is priced at $450. Please contact our laboratory for a list of all genes covered by Array CGH analysis or if you have any other questions about deletion and duplication testing.
Can we only order a few selected genes in a NGS panel and get a discount?
Unfortunately, due to the high throughput setup of our NGS panels, it is not ideal to select specific genes from any panel we offer.
How soon do you update your NGS panels when new genes are identified?
Because of our unique setup, we can easily integrate any new gene into our panel with no additional charge. Therefore, we continue to add new genes to our panels.
Do you confirm mutations identified by NGS with Sanger sequencing?
Yes. We always confirm mutations and novel variations by Sanger sequencing.
Do you charge parental testing?
No. We realize parental testing might not be covered by insurance. Equally important, we always want to further confirm our results in order to be 100% accurate. The additional test becomes our quality control assay.
Do you charge sibling testing?
Yes. We will conduct a specific mutation analysis ($250) for the mutations found in the proband sample. Siblings will be issued an individual report.
How soon can we expect to receive the genetic test report?
Our turn-around time is around three weeks for single genes, and four weeks for NGS. For orders that include parental carrier confirmation, results will be reported in a combined single report with the proband. A separate report can be issued at an extra cost.
How long do blood samples last?
5 days at room temperature.
Do blood samples need to be kept cold?
Blood samples can be sent in an EDTA blood collection tube at room temperature. It can be sent at 4 degrees, do not freeze blood. Specimen requirements are listed in the How to Order a Test section on our website.
Can you receive samples on Saturdays?
We do not receive packages on Saturday, so if the package was sent to arrive then, it will not be processed until Monday. Please plan accordingly with blood samples (do not send samples in a way that will exceed 5 days from collection time).
Do you bill Medicare or Medicaid?
Our lab is not enrolled in these programs, thus we are unable to bill Medicare or Medicaid. Insurance coverage for genetic testing for ocular diseases can be limited. Please contact your insurance company if you are unsure of coverage.
What is your turnaround time (TAT)?
We aim to have the genetic testing completed and results sent out within four weeks of receiving the patient sample and requisition form. However, urgent cases will be completed within two weeks.
