Lab

The SHR Lab domain contains definitions for elements related to laboratory measurements.

ChangeFlag

Indicator of significant change (delta) from the last or previous measurement. C1705241

Value:  CodeableConcept from ChangeFlagVS A set of codes drawn from different coding systems, representing the same concept.

HIVScreeningTest [Entry]

The result of an HIV Screening Test.

Based On Test

Value:  CodeableConcept from HIVScreeningTestResultVS A set of codes drawn from different coding systems, representing the same concept.
ObservationCode must be a TestCode required A term from a controlled vocabulary that defines the data element (the question, not the answer) as specifically as possible. The specific code should always align with the concept of the element, but may be more specific. For example, the concept associated with medications is code for 'medication used', but the ObservationCode is the code for the particular medication used. For tests, ObservationCode identifies the specific test being performed, and for observations, the specific question being asked.
         where  TestCode from HIVScreeningTestCodeVS required The code for a laboratory, radiologic, and other clinical test or measurement that helps to determine the presence, absence, or degree of a condition, or assess the health of an individual.
ObservationMethod must be a TestMethod optional The method of the observation, for example, the specific imaging technical or assessment vehicle.
BodySite optional Location on or in the body.
BodyPosition optional The position or physical attitude of the body.
Device optional A specific durable physical device used in diagnosis or treatment. The value is the coding for a type of device, for example, a CPAP machine. The same device might be used on multiple patients.
Specimen (TBD) optional Description TBD
Interpretation optional A clinical interpretation of a measurement.
ReferenceRange optional The usual or acceptable range for a test result.
ChangeFlag optional Indicator of significant change (delta) from the last or previous measurement.
TestRequest optional A record of a request (order) for a test to be performed.
ObservationCategory 0 or more A categorization of the observation according to how the observation was collected or its clinical area.
ObservationReason optional The reason for making the observation.
ObservationNonOccurrenceModifier optional True if the observation did not occcur, e.g., if a test was not performed or the assessment was not done, when it might otherwise be expected.
ObservationStatus required A qualifier describing the stage or administrative state of the observation. If not given, it is assumed the status is final.
ObservationQualifier 0 or more A description of the conditions or context of an observation, for example, under sedation, fasting or post-exercise. Body position and body site are also qualifiers, but handled separately. A qualifier cannot modify the measurement type; for example, a fasting blood sugar is still a blood sugar.
ClinicallyRelevantTime optional The time or time period that the observation addresses. The clinically relevant time is not necessarily when the information is gathered or when a test is carried out, but for example, when a specimen was collected, or the time period referred to by the question. Use a TimePeriod for a measurement or specimen collection continued over a significant period of time (e.g. 24 hour Urine Sodium).
Participant 0 or more A statement about an actor who did (or did not) participate in a certain task or activity. Unlike a HealthcareInvolvement which continues over period of time, the participant is associated with doing or not doing a specific task, such admitting a patient, performing a procedure, or taking a measurement.
Setting 0 or more Description of the place or type of surroundings where something is positioned or where an event takes place.
Location 0 or more A position, site, or point in space where something can be found.

Other examples include do not ambulate, do not flush NG tube, do not take blood pressure on a certain arm, etc. If the Request.code and RequestAgainstModifier both contain negation, that will reinforce the prohibition, and should not be interpreted as a double negative that equals a positive.
RequestedPerformanceTime optional When test or tests should be done. If the tests are a series or recur (e.g. daily blood sugar testing in the morning) then a Timing can be used to describe the periodicity.
Reason optional The justification for an action or non-action, conclusion, opinion, etc.
