100
The time interval at which each technician should be tested for their competency in a particular skill.
What is semiannually in the first year following training and then annually thereafter.
100
Name at least 2 of the 4 unique identifiers that are acceptable for labeling all specimen samples.
What are Patient Name, Date of Birth, Social Security Number, Accession Number/Requisition Number. LIMS Barcode is also an acceptable answer.
100
TRUE/FALSE Samples, equipment, and PPE can be transported back and forth between Pre- and Post- Laboratories as needed.
What is False. Workflow should remain from Pre to Post and never the reverse. PPE is to remain in the laboratory they originated in.
100
TRUE/FALSE Control samples can be processed before, along side, and/or following their associated Clinical Samples.
What is False. Control Samples are to be processed at the same time, by the same technician, with the same reagents/equipment as the Clinical Samples.

The control that monitors specifically for contamination within the method's reagents. (Library Prep and/or Amplicon PCR)
What is a Non-Template Control, a Water Blank, a Negative Control, or a 'No DNA' Control.
300
The system of recording of lot numbers, expiration dates, date received, and date placed into service, so that the labs are sufficiently stocked.

What is the dedicated CAP telephone line for GeneDx employees to communicate concerns about quality and safety management.
300
The best practice for when there is an error in patient identification or other information on a specimen label.
What is recollect the specimen? If that is not possible, label correction should be documented and a Corrective Action put into place.
300
Separate rooms or a separation barrier has been implemented to prevent contamination and is mandatory for successful test results.
What is Pre and Post PCR areas?
300
This spike-in helps to monitor sample to sample contamination.

The procedure when patient test results cannot be reported out within established time frames.
What is GeneDx is obliged to notify the appropriate individual/client that there will be a delay of testing.
400
In order to reduce the possibility of a sample switch, this number of DNAs may be open at one time during a hand amplification.
What is one DNA?
400
This reagent/standard allows for the multiplexing of several patient samples into one lane during sequencing.
What are the i7 and i5 Indexes.
500
In order to assure all copies of a policy/procedure are up to date, personnel have read those policies, and that all policies have been authorized by the lab director prior to implementation, this system was put into place.
