Pre-natal Tests
95% of Pre-natal requests will be reported within 5 working days provided appropriate material and information is sent.
Cost : £143 which includes MCC exclusion using microsatellites

NOTE:  Please contact the laboratory to discuss Pre-natal and other Urgent testing before collecting the sample; this will ensure that the laboratory can issue a report as quickly as possible.

Predictive Testing
95% of referrals where a pathogenic mutation has been identified in an affected family member will be issued within 10 working days, provided appropriate material and information is sent.
Cost: £130 for sequence analysis with 2 primer sets
£143 for MLPA

Full Screen
For those disorders highlighted in italics, please indicate the level of screening required. 
Where MLPA is requested as part of a full screen, a single report will be issued when the screening is complete and the reporting time will be 40 working days.
