Parental Sample Prep for Prenatal Microarray Testing

Method Description Describes how the test is performed and provides a method-specific reference

The heparinized sample will be cultured following standard laboratory protocols and a fixed-cell pellet will be prepared. DNA will be extracted from the EDTA sample and used to perform maternal cell contamination testing on the maternal sample. The fixed cell pellet and DNA will be stored in the laboratory for possible confirmation testing if an abnormality is detected on the prenatal array sample.(Unpublished Mayo method)

Day(s) and Time(s) Test Performed Outlines the days and times the test is performed. This field reflects the day and time the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time required before the test is performed. Some tests are listed as continuously performed, which means assays are performed several times during the day.

Specimens are processed Monday through Sunday.

Results reported Monday through Friday, 8 a.m. to 5 p.m.

Analytic Time Defines the amount of time it takes the laboratory to setup and perform the test. This is defined in number of days. The shortest interval of time expressed is "same day/1 day," which means the results may be available the same day that the sample is received in the testing laboratory. One day means results are available 1 day after the sample is received in the laboratory.


Specimen Retention Time Outlines the length of time after testing that a specimen is kept in the laboratory before it is discarded

4 weeks

Performing Laboratory Location Indicates the location of the laboratory that performs the test
