labitems with same label, fluid, & category but different itemid

[MEladawi]

Hi--

I wanted to report this and I don't know if you did that intentionally or not.

Some lab measurements in (mimic_hosp.d_labitems) have the same label, fluid, category, & units (in mimic_hosp.labevents) but have different itemids.

I realize the loinc_code is assigned to one only, but should they be merged with the same loinc_code?

Example:

Also, some items have different itemids just because the units used in the labevents table are different:

Thank you!
