Our Services

Comprehensive genetic testing and counseling across 20 organ systems.

🧬

Diagnostic Genetic Testing

Our core service: identifying the molecular basis of suspected genetic conditions. We evaluate patients across all 20 organ systems using the most appropriate testing strategy for each clinical presentation.

  • Unexplained symptoms across any organ system
  • Family history suggestive of genetic condition
  • Failed prior diagnostic workup
  • Confirmation of clinical diagnosis

Rapid Critical Care Genomics

Time-critical genetic diagnosis for critically ill neonates and children. Rapid exome and genome sequencing delivers results in 3–7 days, when every hour matters.

  • NICU: 34–59% diagnostic yield, 25% LOS reduction
  • PICU/CICU: 31–59% yield, 80% management change rate
  • 3–7 day turnaround for rapid sequencing
  • Diagnosis within the admission, before the odyssey begins
👪

Carrier Screening & Reproductive Genetics

Genetic evaluation for family planning, including carrier screening for prospective parents, prenatal genetic assessment, and reproductive decision support.

  • Pre-conception carrier screening
  • Prenatal genetic evaluation
  • Cascade family testing
  • Reproductive risk counseling
💊

Pharmacogenomics

Genetic profiling to guide medication selection and dosing. Identify how your genetic makeup affects drug metabolism to optimize treatment and prevent adverse reactions.

  • Medication response profiling
  • Adverse event risk prediction
  • Dosing optimization
  • Multi-drug interaction assessment

Testing Methodologies

We select the right test for each clinical scenario based on evidence and indication.

Gene Panels

Targeted analysis of specific genes associated with a known clinical presentation. Best when the phenotype strongly suggests a specific group of conditions.

Turnaround: 2–4 weeks

Exome Sequencing

Analysis of all protein-coding regions of the genome (~20,000 genes). The most common comprehensive test for undiagnosed conditions.

Turnaround: 4–8 weeks

Genome Sequencing

Complete analysis of the entire genome, including non-coding regions. Captures structural variants and intronic changes that exome sequencing may miss.

Turnaround: 6–10 weeks

Rapid Sequencing

Expedited exome or genome sequencing for critically ill patients in intensive care settings where timely diagnosis directly impacts management.

Turnaround: 3–7 days

The CarePathways Approach

Every patient follows a structured diagnostic pathway from first contact to follow-up care.

Referral
Your provider refers you, or you contact us directly. We review your clinical history to determine the best path forward.
Genetic Counseling
Meet with a certified genetic counselor to discuss your history, testing options, benefits, limitations, and what to expect.
Testing
A simple blood draw or saliva sample is collected. We select the most appropriate test based on your clinical presentation.
Results & Follow-Up
Results are reviewed in a dedicated appointment. We explain findings, discuss implications, and coordinate next steps with your care team.

Insurance & Coverage

Most genetic testing is covered by insurance when medically indicated. We work with all major insurance carriers and provide prior authorization support to ensure coverage before testing proceeds.

Typical testing costs range from $250 to $3,000 depending on the type of test ordered. Many patients have minimal out-of-pocket costs when testing is medically necessary.
