Does labevents include the patient's laboratory test records during the ICU?

[huangzhuohua]

There is a labevents table under the mimiciv_hosp schema. Does its data include the test data of the patient during the stay in the ICU? Or are the test data of the patient during the stay in the ICU only stored in chartevents under the mimiciv_icu schema?

Yes, the labevents table stores all laboratory measurements for the patient, independent of whether they are in the ICU or not. There are duplicate lab measurements in the chartevents table, which you should be aware of. If you are using MIMIC-III, these measurements may be off by 1-hour due to a bug (see #784). Personally I stick to using labevents only, most of the time.
