TISSUE CULTURE & CYTOGENETICS
Background
WRGL offers a comprehensive range of services for pregnancy loss, post mortem and postnatal tissue samples. This includes tissue culture, karyotyping, DNA extraction, QF-PCR, snap freezing for future testing and a send away service. In appropriate cases cultured cells can under go cryopreservation.
Tissue Testing at WRGL
WGLR offers tissue culture, karyotyping, QF-PCR, DNA extraction and frozen sample storage for postnatal and post mortem tissue samples where chromosomal or genetic abnormalities are suspected. Every attempt is made to culture tissues from missed abortions, stillbirths and perinatal deaths so a full karyotype result can be provided. If this is not possible the sample will be tested by QF-PCR for common aneuploidies. Maternal cell contamination testing is also available as required. Fixed cells can also be prepared and stored for any future cytogenetic testing.
