tblLAB_RES - Resistance testing


holds background information on the resistance test, laboratory, library, kit, software and type of test

Note: This table is tightly linked to tblLAB_RES_LVL_1, tblLAB_RES_LVL_2 and tblLAB_RES_LVL_3.

Resistance should be reported at lowest level of interpretation possible – so if the nucleotide sequence is available this should be reported rather than the list of mutations or resistance scores. However, the resistance test results should be captured if they have been part of the physician’s treatment decisions for the patient.

Non-amplifiable resistance tests should not be reported.

These four tables are designed to capture several possible formats the clinics and cohorts might have recorded resistance test data in. Once this data is gathered it should like all other tables be quality assessed.

Core Fields

Note: Fields marked bold form the unique identifier for a record of the table.
Field name
Format
Description
PATIENT
character (or numeric if possible)
Code to identify patient (Cohort Patient ID)
TEST_ID
character (or numeric if possible)
An arbitrary value identifying a resistance test result
SAMPLE_D
yyyy-mm-dd
Date of the actual sample taken (NOT the test date)
SAMPLE_D_A
character: see coding of date precision
optional precision annotation for date of sample
SEQ_DT
yyyy-mm-dd hh:mm
Date and time when the sequencing was performed
SEQ_DT_A
character: see coding of date precision
optional precision annotation for date of sequencing
LAB
character
Name of laboratory where the test was performed
LIBRARY
character
Library/algorithm used to identify resistance mutations
REFSEQ
character
Name/identifier of reference strain used to find mutations
KIT
character
Vendor and version/name of the kit used for the test
SOFTWARE
character
Software and version used to determine resistance
TESTTYPE

numeric:

  • 1 = Genotype (e.g., GeneXpert, NAAT/LPA
  • 2 = Phenotype (e.g., culture)
  • 9 = Other
Type of test
TESTTYPE_M

character:

  • SSQ = Sanger sequencing based
  • NSQ = Next generation sequencing
  • other, Other
Type of method used
PATHOGENTYPE
character: MeSH terminology ​https://meshb.nlm.nih.gov/search
Type of pathogen
VIRUSTYPE

numeric:

  • 1 = HIV
  • 2 = HCV
Type of Virus
SUBTYPE
character
Subtype of HIV- or HCV-RNA

Additional Fields

As shown with the core fields, the TEST_ID is the link between the 3 levels of data and the test background information table.

Some prior assessment of the assigned test identifiers has to be done in order to avoid duplicates.

In a running database the duplicate issues are easily resolved by adding a unique auto-generated key as the identifier between 3 levels of data and the test background information table.

Along with the TEST_ID it might be necessary to store the ID assigned to the sample at both the testing laboratory but also the centres laboratory in order to track the sample.

Field name
Format
Description
SAMP_LAB
character (or numeric if possible)
The assigned sample ID at the lab where the resistance test is preformed.
SAMP_INT
character (or numeric if possible)
The assigned sample ID from the centre.
