ResidentData/CovidTests
Information on Covid-19 diagnostic tests on CDCR residents administered by or reported to CDCR from the beginning of the pandemic to the present.
General comments
This table comprises one record per CDCR resident per day for each positive, negative, and inconclusive SARS-CoV-2 diagnostic tests. If, for example, a resident had a negative and a positive diagnostic test on the same day, there would be two records for that resident for that day in this dataset. If a resident had two negative tests on the same day, there would be one record for that resident on that day, based on the first of the two tests received. Pending tests are not included unless and until a result is received. Tests collected while residents are in community facilities may also be included in the dataset even though the resident is not residing in a prison at the time.
ResidentId
Stable anonymized signed integer ID value for the resident
- Examples
578998371, -456578293
Institution
The facility where the test was collected, including non-CDCR locations. This is often a CDCR prison but may also be a community facility, a jail (county name is used in this case), or other location. In some cases, the facility is unkonwn and the resident's presumed location at the time of test collection is used (e.g., CDCR, PAROLE, DISHCARGED, ESCAPE).
- Examples
ASP, CCWF, Butte County, El Dorado County, CDCR, PAROLE
CollectionDate
the collection date of the test. In cases of clear data entry error for this date, CollectionDate is adjusted to equal ReceivedDate. In these cases the term "(CollectionDate adjusted)" will appear in the Details column string.
Result
The result of the diagnostic test. Result of a positive, false positive, negative, or inconclusive SARS-CoV-2 diagnostic test collected on the date indicated by the Day value of the record. In cases where multiple positive tests, multiple negative tests, or multiple inconclusive tests are collected on the same day for the same resident, the first received test with that result is used.
- Values
Negative, Positive, Inconclusive, FalsePositive
ReceivedDate
The date the diagnostic test result was received.
- Examples
2020-12-01, 2021-02-09
Limitations
The date the test result was received is often unreported. In cases where the received date exists but precedes CollectionDate, it is automatically set equal to CollectionDate.
Details
Test type, viral load, and/or identified variant for the SARS-CoV-2 diagnostic test. Values are separated by a | (pipe), followed by the type of information provided. In cases of multiple tests with the same result on the same day, descriptors and values for each test are included. Detail types are as folows:
|Type
The type of test collected. Note: A single test may have multiple |Test_type entries in the details column.
- Examples
- |Type_type Antigen FIA Test
- |Test_type SARS CoV 2 RNA (COVID19)
- |Type_type Antigen FIA Test |Test_type SARS CoV 2 RNA (COVID19)
- |Test_type BinaxNow POC
|Ct_RLU
The Ct or RLU value(s) for the test. Only provided for positive tests. For most tests, no Ct or RLU value is available.
Examples
- |Ct_RLU 23.4716
- |Ct_RLU 1270
- |Ct_RLU 17.7 / 16.8
|DateCollected adjusted
Indicates that that the collected date was adjusted due to data entry error
Values
- |DateCollected adjusted
|SNP
The SARS-CoV-2 variant. Based on variations of single nucleotide polymorphisms.
Examples
- |SNP Delta
- |SNP Omicron
- |SNP Indeterminate
- |SNP Not detected
|WGS
The SARS-CoV-2 Pango lineage. Based on whole genome sequencing.
Examples
- |WGS AY.25
- |WGS B.1.429
- |WGS Insufficient RNA
- |WGS Failed
|WGS_Lab
The lab that conducted the sequencing.
Examples
- |WGS_Lab VRDL
- |WGS_Lab CDC
- |WGS_Lab UCLA-XL
Limitations
Due to labeling differences across laboratories and across time and data entry errors and omissions, test types may be misdescribed or incomplete. All tests in this dataset are Covid diagnostic tests, discrepant descriptions notwithstanding.
GisaidId
This detail is not currently available.
The GISAID ID associated with the test.
ViralSequence
This detail is not currently available. The viral genomic sequence of the test specimen.
