This is an example of a positive COVID result using one potential LOINC code. Please note that LOINC information may change as this was an urgent release. Other possible LOINC codes are noted in comments of the example

This is an example of how to encode positive and negative, which are common data types returned form lab equipment. While some technologies may represent this as a type of ST (string), it is logical and easily possible to encode this information using SNOMED-CT. This would allow structured examination of this information downstream as well as comparison to a structured reference range, as shown in the example. Previously the examples task force approved this sample with the data type Coded Ordinal (CO) with the example name: Result panel with two ordinal values of negative-positive. The examples task force received feedback during implementation that CO is not commonly used, and CD is preferred. Updated the sample name to Result panel with coded values of negative-positive

This is an example of a value from a lab result with multiple reference ranges: Negative (less than), Bordeline (equal), and Positive (greater than).

This is an example of a value from a lab result that may not be structured.

This is an example of how to encode "greater than" (but not equal to) a specific range when returned from lab equipment. The example is for a point-of-care glucometer, which measures blood sugar for diabetics. Often these devices may have an upper bound, 500 mg/dL is shown in this example. An inclusive tag of false is shown to demonstrate a non-inclusive range. The upper bound of the interval is positive infinity in this example. This example also includes two structured reference ranges for normal and high.

This is an example of a results panel with Laboratory Location details as required by 2015 Certification Sender test 170.315(e1), in compliance with 42 CFR 493.1291(c)(1) through (7).

This is an example of a value from a lab with a discrete unit, but whose value is not a number, so the PQ datatype, the only type with a unit attribute, cannot be used.

This is an example of how to show a radiology result with narrative report in the results section. For the value, xsi-type equals ED (with reference) for encapsulated data.

This is an example of a value from a lab which didn’t include a UCUM unit.

Sample from Meaningful Use test data (inpatient data)

This example illustrates how to structure Laboratory Tests and Values/Results for the 170.314(b)(2) Transitions of care - I) Laboratory Tests and Values/Results.

This is an example of a results panel with pending component.

This is an example of how to encode "less than or equal to" a specific range when returned from lab equipment. The example is for BNP, an immunoassay where the lower threshold for detection is often 5 pg/mL. The lower bound of the interval is zero in this example, even though this is none may be specified, since zero is the lower bound for measures of physical quantity. This example also includes a structured reference range.

This is an example of a value from a lab which requires a translation for its unit. All units for physical quantities should be represent in UCUM.
