Each lab is imported with a value.

=== Lab_DtTm ===

The field '''Lab_DtTm''' in [[L_Labs_DSM table]] is generated as follows from the inconsistenly populated fields in the export:

* <code>LabDtTm_str = "CDate(Nz([COLLECTEDDATE], [arriveddate])) + CDate(Nz([CollectedTime], [LabarrivedTime]))"</code>

** ie use collected dttm if available, else use arrived dttm

=== Start of date range ===

The Lab_DtTm is compared to the admit time of the patient as follows:

* <code>" WHERE ([Admit_DtTm]<=" & LabDtTm_str & ") AND (" & LabDtTm_str & "<=nz([Dispo_DtTm],now())) "</code>

** ie we start the range with the [[Admit DtTm]]

=== date constraints ===

the data we would want to use, but instead on which data was consistently available. Not all these columns are always filled.

*<code>[Arrive_DtTm]<=CDate(Nz([COLLECTEDDATE],[arriveddate]))+CDate(Nz([CollectedTime],[LabarrivedTime]))</code>

*<code>CDate(Nz([COLLECTEDDATE],[arriveddate]))+CDate(Nz([CollectedTime],[LabarrivedTime]))<=[Dispo_DtTm]</code>

=== counts ===

We originally did labs as counts, but now store them with results. A count of them can be viewed using query ''L_Labs_Flowsheet_DSM_sum''.

=== individual record ===

Most of the lab tests we count are one DSM line per lab done, and the best way to identify them was based on the TESTCODE column in the [[DSM Lab Extract]].

Most of the lab tests we count are one DSM line per lab done, and the best way to identify them was based on the TESTCODE column in the [[DSM Lab Extract]]. hat column is compared to table ''s_mapping_lab'' by query ''2_D_counts_test_appender'' to populate table ''L_Labs_Flowsheet_DSM''.

=== group of records ===

Some other lab tests lead to multiple results and are reported as a group of lines per lab done. The best way to identify them was based on the GRPTEST column in the [[DSM Lab Extract]].

Some other lab tests lead to multiple results and are reported as a group of lines per lab done. The best way to identify them was based on the GRPTEST column in the [[DSM Lab Extract]]. That column is compared to table ''s_group'' by query ''2_D_counts_group_appender'' to populate table ''L_Labs_Flowsheet_DSM''.

The s_mapping_lab table in [[Instructions for importing a batch of DSM Data]] defines which labs will be counted as which tests.

On every run of [[Instructions for importing a batch of DSM Data]], there is a check to find out if any new labs are in the new data that are not in the table. During testing, most times included a few new labs. For these new labs it would need to be decided if they are a type we collect before finishing the import.

== Updates / new lab Name or Labels in DSM ==

The [[Instructions for importing a batch of DSM Data | import process]] checks for values not previously seen on each import. If there are new ones it adds them to the list and alerts the user to decide if they should count toward one of the labs we collect.

The import function checks for values not previously seen on each import. If there are new ones it adds them to the list and alerts the user to decide if they should count toward one of the labs we collect.
