Procedure for collection of sample


  • Dr Edward Chandraratnam collects the sample under ultrasound control.


  • The first sample is collected only to check for adequacy. No report will be issued.


  • Two additional samples are collected in transport medium and the refrigerated specimen is air-freighted (Fed Ex) to Veracyte Inc. in San Francisco, USA. 


  • Specimens are collected on Monday or Tuesday. This ensures that the sample will reach USA on a working day and not over the weekend.
