How to submit information in the Ordering section of the submission form

This page is organized according to the sections you see on the Ordering tab. You can click on the name of the section below to navigate to that section of this document.

Please note that most sections in the form provide tool tips, accessible by this icon (help icon), that provide hints specific to that area.

Ordering information

Each test is a specific, orderable test from a particular laboratory, and each receives a unique GTR accession number. The same or similar test performed by different laboratories is assigned a different accession number. Thus, a laboratory is free to define an orderable test exactly as they represent it in their test catalog.

Test order code (recommended). Enter the test order code, commonly found on the laboratory's requisition form, test menu or test catalog. This is the code health care providers (for example) would use to order the test through the laboratory.

URL of the lab website with information about this test (recommended). Enter the URL for test-specific information on your laboratory's website. URLs should be entered with the appropriate prefix, i.e., http:// or https://.

How to order (recommended). Enter a description of the test ordering procedure, such as required forms, specimen handling/shipping instructions, etc. Requirements and recommendations about informed consent can be discussed here.

URL of the lab website with information about how to order this test (recommended). Enter the URL for information on how to order the test. URLs should be entered with the appropriate prefix, i.e., http:// or https://.

Sample collection and transportation requirements (optional) Describe instructions for proper processing of the sample. You may include instructions for collecting a sample. Specify container, volume, storage, temperature, causes for rejection, and days that samples may or may not be received.

Turnaround time (optional) The usual number of hours or days between the time a specimen is received and a result is released. Specify the time unit (e.g. "2-3 days").

Specimen source (recommended). Select the specimen type(s) allowed for the test. Multiple selections allowed. Choices include: Amniotic fluid, Bone marrow, Bronchoalveolar lavage, Buccal swab, Buffy coat, Cell culture, Cerebrospinal fluid, Chorionic villi, Cord blood, Fetal blood, Fresh tissue, Frozen tissue, Nasal aspirates, Nasal swab, Nasopharyngeal (NP) swab, Nasopharyngeal washes, Oropharyngeal swab, Other, Paraffin block, Peripheral (whole) blood, Plasma, Product of conception (POC), Saliva, Serum, Skin, Sputum, Throat swab, Urine, White blood cell prep; Other: please specify.

Specimen requirement URL (recommended). Enter the URL to the laboratory's website that describes the specimen requirements and handling for the test. URLs should be entered with the appropriate prefix, i.e., http:// or https://.

AMA CPT Code(s)

AMA CPT MoPath code(s) (optional). AMA CPT code provided as guidance to assist clients with billing for this test. Enter one per line.

NOTE: NLM does not have a license to represent other CPT codes, only the MoPath (Molecular Pathology subset) codes. MoPath codes have the format '81XXX'. Please do not submit other CPT codes via spreadsheet or validation errors will result.

In order to view code descriptors and submit AMA CPT codes, the AMA license agreement must be accepted (once per submitter). If you have not yet accepted the agreement, you will see a link 'Click here to view the AMA license agreement', click on the link to review and accept the agreement as shown below. (If your laboratory has a group set up for GTR submissions, other submitters in your group will need to accept the AMA license agreement in order to edit CPT codes.)


Once you have accepted the AMA license agreement, the link "Add AMA CPT Code" will be enabled for you to submit the codes that are applicable to the test.

To find and select codes, you can search for any text in the descriptor such as code number, gene symbol or gene name, condition name, common names of variants, or test methods. Use the Enter key or click the Search button. To see all available AMA CPT MoPath code choices, click 'Show all'.

Search CPT codes

Highlight the appropriate code from the codes found by your search and click "See more". This will display the full text summary description of the specific code. Determine whether the code correctly represents your test; if so then click the "Select" button.

You can enter as many codes as are applicable to you test by clicking the link "Add AMA CPT code". The codes you select will display on the 'How to Order' tab of your test and will be hyperlinked to the AMA descriptor for that code.

Z-code(s) (optional) Enter the Z-Code Identifier for this test. The Z-code is a 5-character alpha-numeric code associated with certain molecular diagnostics (MDx) tests used in addition to the CPT code, to help payers and providers clearly understand which test is being ordered, performed, and billed.

LOINC code(s) (optional). The LOINC (Logical Observation Identifiers Names and Codes) database provides a set of universal names and ID codes for identifying laboratory and clinical test results. Enter the LOINC code. If applicable, the LOINC code can be found by using the 'Search' link, which will take you to the official LOINC website. The LOINC code must be entered manually, even if the submitter searches for the code using the link provided.

URL to lab website with information about codes related to this test (recommended). Enter the URL for information on corresponding codes related to the test, including CPT, ICD-9, ICD-10 and HCPCS codes. URLs should be entered with the appropriate prefix, i.e., http:// or https://.

Who can order this test? (optional). Identify who can order the test based on the laboratory's policy on how the test can be ordered. Multiple selections can be made.

Choose from the following options:

Genetic counselor
Health care provider
In-state patients
Licensed dentist
Licensed physician
Nurse practitioner
Out-of-state patients
Physician assistant
Public health mandate
Registered nurse

Ordering requirements

Information in this section conveys whether or not a sample may be accepted and processed based on requirements for informed consent. If specific laboratory forms relating to these types of requirements must accompany the sample, instructions and URLs to relevant forms can be given in the ‘How to order’ text box above.

Informed consent (recommended). Identify if the laboratory requires informed consent prior to performing the test. Select from the following choices: Decline to answer, required, not required, based on applicable state law.

Test-specific laboratory services (optional). If applicable, select the laboratory services that are offered in conjunction with the specific test. Multiple selections are allowed. Please select each test service only once (you can provide multiple order codes for one service) in the order code field. This field is different from 'Laboratory services' which allows submitters to select general services the laboratory provides.

Choose from the following options: Data Storage and Backup
Result Interpretation

Order code (optional). If applicable, enter the order code for the test-specific service, commonly found on the laboratory's requisition form, test menu or test catalog. This is the code health care providers (for example) would use to order the service through the laboratory.

Comment (optional). Enter further information to assist health care providers in ordering the test-specific services.

Testing strategy (recommended). Describe the suggested sequence of ordering tests, discuss reflex testing, testing algorithms and related issues. This field is for recommendations on how to order the test in sequence of relevance to the patient (target population) being tested. This field should not include discussion of methodologies or test procedural protocols. If describing reflex tests, each test component should be delineated. If a test is ordered, additional tests may be performed as necessary under certain circumstances based on initial results and that should be described in this field.

Citations for testing strategy (recommended). Enter references and/or URLs as appropriate to further describe the testing strategy/algorithm. If entering an URL, please specify the appropriate prefix, http:// or https://.

Test-specific contact information

Contact person (recommended). From the personnel listed, select the test-specific contact for the test. This individual's name and contact information will be displayed on the test page for health care providers to view. If no test-specific contact is provided, the laboratory's general contact information will display. 

Note: If you do not see the staff member's name you want to select in the personnel list, you will need to add the staff member in the laboratory section. If the staff member is entered on the laboratory personnel list, but does not display in the test-specific contact list, check the staff member's privacy settings by reviewing the selection 'Should this person's information be displayed on the GTR public site?'. If 'No' is selected, the staff member will not display in the test-specific contact list, nor on the public website. If changes to personnel are needed, please save your work on the test and then proceed to editing your laboratory information in order to add new or edit existing staff members. Once submitting the laboratory changes, the newly entered staff information should display in the test contact person field.

Deleting a staff member from the personnel list in the laboratory section will remove that staff member from any tests they are a test-specific contact for. If a staff member has 'No' selected for 'Should this person's information be displayed on the GTR public site?', they will not display as test-specific contacts, even if 'No' is selected after indicating they are a test-specific contact.

Contact policy (recommended). Select the policy of the laboratory regarding who (patients or health care providers) and when (pre-test/post-test/anytime) can contact the lab for this test. Options include:

  • Laboratory can only accept contact from health care providers. Patients/families are encouraged to discuss genetic testing options with their health care provider.

  • Post-test email/phone consultation regarding genetic test results and interpretation is provided to patients/families.

  • Pre-test email/phone consultation regarding genetic test results and interpretation is provided to patients/families.
