Test Catalog

Test ID: CULAF    
Culture for Genetic Testing, Amniotic Fluid

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

The specimen is split into 8 to 10 separate culture dishes. The cells are grown on coverslips in culture media for 4 to 10 days. The cultures are trypsinized into 2 to 3 T25 tissue culture flasks or 1 to 2 T75 tissue culture flasks.(In The AGT Cytogenetics Laboratory Manual Fourth edition. Edited by MS Arsham, MJ Barch, HJ Lawce. John Wiley and Sons Inc 2017, 175-178)

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.-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.

23 days

Maximum Laboratory Time Defines the maximum time from specimen receipt at Mayo Clinic Laboratories until the release of the test result

24 days

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

Cell cultures: 6 months; Any remaining supernatant or whole fluid aliquots: 14 days after results reported.

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