Diagnostic and companion testing
Advanced approaches for invaluable insights
Diagnostic and companion testing can provide definitive answers when there is a family history of genetic illness or additional information is needed to clarify chromosomal abnormalities or other conditions suggested by carrier screening, ultrasound, or alternate methods.
Our diagnostic and companion assays were carefully developed to protect and preserve fetal specimens to ensure all appropriate analyses can be performed. The ability of our laboratory to perform all types of prenatal testing — from culture to advanced genetic analysis to companion testing — translates into streamlined efficiencies that promote faster results. Because we understand the urgency for accurate answers, we prioritize customer support to ensure ordering physicians receive results as quickly as possible.
Diagnostic and companion Test menu
Companion testing
Our companion test offerings support cytogenetic and molecular testing approaches, helping to ensure appropriate testing can be performed and accurate results.
Key testing
- CULAF | Culture for Genetic Testing, Amniotic Fluid
- CULFB | Fibroblast Culture for Biochemical or Molecular Testing, Chorionic Villi/Products of Conception/Tissue
- MATCC | Maternal Cell Contamination, Molecular Analysis, Varies
- PPAP | Parental Sample Prep for Prenatal Microarray Testing, Blood
Cytogenetic testing
Chromosomal analysis can identify genetic conditions associated with structural and numerical chromosomal irregularities, such as aneuploidy.
