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

PAPP-A is pregnancy-associated plasma protein A and is a sequential immunoenzymatic assay that uses two monoclonal antibodies and external calibrators.

 

AFP and hCG are both measured using a non-competitive immunoassay that uses one antibody to capture the protein to a solid phase, another antibody to detect the protein, and external calibrators.

 

The estriol assay is a solid phase competitive immunoassay that uses an anti-estriol polyclonal antibody, labeled estriol, a solid phase antibody directed against the estriol antibody, and external calibrators.

 

Inhibin-A is measured using a non-competitive microtiter immunoassay that uses a detection antibody to subunit a, a capture antibody to inhibin subunit BA, and external calibrators.

 

Calculation of post-test risks uses a multivariate log Gaussian model. Risk estimates for DS and T18 are influenced strongly by maternal age.

No

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.

Sunday - Saturday

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.

2 - 4 days

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

4 - 8 days

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

ARUP Laboratories
