Minimum volume for an optimal result is greater than or equal to 5 mg. Samples less than 5 mg may result in inconclusive results and a repeat sample may be requested.
Reflex Testing
If an abnormality is detected the Cytogenetics Director will determine the appropriate additional studies (e.g. C-banding, NOR) to be performed to characterize the abnormality.
If additional metaphases are required for final interpretation additional counts will be performed and billed for.
Additional testing may be omitted if specifically requested when the sample is submitted for cytogenetic analysis.
