All reporting times are from sample receipt at the laboratory.
For detailed information see the relevant service profile.
Biochemical Genetics
Reports are issued without delay, usually within 24 hours of
results being obtained.
Telephone results are followed by written results within 24
hours.
Cytogenetics
Prenatal samples (rapid aneuploidy
screening)
2-3 working days if received up to 2.00pm.
3-5 working days if received after 2.00pm.
Preliminary telephone results for exclusion of aneuploidy are
normally available within 2 working days.
Prenatal samples (amniotic fluid and CVS)
10 days average, dependent of rate of cell growth.
Prenatal samples (direct CVS preparations)
Normally 2-5 days when the result is abnormal and concurs with
abnormal ultrasound
findings. Results from direct CVS preparations should never be
considered definitive.
Prenatal samples (fetal blood)
4-5 working days.
Prenatal FISH Tests
Results reported simultaneously with routine cytogenetic
studies.
Postnatal urgent blood samples
10 days.
Postnatal routine blood samples
28 days.
Postnatal solid tissue samples
28 days, dependent of rate of cell growth.
14 days for unsuccessful cell cultures.
Molecular Genetics
Prenatal diagnosis
3 working days.
Testing for known mutations / non-urgent
samples
10 working days.
Testing for unknown mutations (e.g., mutation scanning,
linkage analysis)
40 working days.
