LOINC description : Definitions of answer codes for reason for newborn screen lab test in dried blood
spot: Initial Screen: This answer code is used for the first screen performed on an
infant after birth. When the first specimen obtained is of unacceptable quality and
cannot be used, a replacement specimen is still considered the initial screen. When
an initial screen is performed before 24 hrs because of a planned transfusion or an
extremely ill infant, it is still considered the initial screen even though it may
need to be repeated later. Subsequent screen - required by law: This answer code is
used for mandatory second screens as required by law and assumes that the first screen
was normal and that the second screen was performed only because it was mandated by
law. For example, [give name of state(s)] currently performs a second screen on every
infant born in the state at a particular point in time, such as between 1 and 2 weeks.
The purpose of identifying the reason for a subsequent screen is that it will change
the expected time interval when the subsequent screen should be performed. Subsequent
screen - required by protocol: This answer code is used for subsequent screens that
are performed because of clinical conditions in the newborn that require a repeat
screen as specified by a protocol to assure valid test results. Many of these subsequent
screens have abnormal or out-of-range results on the initial screen that can be explained
by the clinical condition of the infant. Typical examples include premature infants,
infants who receive blood product transfusions, and infants who are receiving intravenous
alimentation. This category should not include abnormal tests that should be considered
presumptive positives (which would require a diagnostic evaluation rather than a repeat
screen by protocol). The purpose of identifying the reason for a subsequent screen
is that it will change the expected time interval when the subsequent screen should
be performed. Subsequent screen - for clarification of initial results (not by law
or protocol): When the results of the initial screen are abnormal or out of range,
many states perform an immediate repeat screen to confirm the results before considering
the test a presumptive positive that will require a diagnostic evaluation. Many of
these results may be considered or reported as equivocal or borderline until a clear
abnormality is confirmed on the subsequent screen. This category does not include
abnormal or borderline results for which there is a clear clinical explanation, such
as prematurity, for which there is a clear protocol for obtaining a second screen.
The purpose of identifying the reason for a subsequent screen is that it will change
the expected time interval when the subsequent screen should be performed. Subsequent
screen - reason unknown: The purpose of identifying the reason for a subsequent screen
is that it will change the expected time interval when the subsequent screen should
be performed. States should use this answer code if they are unable to identify the
specific reason for a subsequent screen, but they are able to separate initial screens
from subsequent screens. The reason for the second screen might be any of the above.
A repeat initial screen because the first specimen was of unacceptable quality should
not be considered a subsequent screen, but some states may use this code if they are
unable to track that the reason for a second specimen was unacceptable quality of
the first screen. No sample collected due to parental refusal: This answer code is
used to document parental refusal of newborn screening so that a report can be generated
which will contain no test results because no specimen was submitted. This will enable
complete matching of newborn screening results to all infants born even if no laboratory
testing was performed.;
