Question about d_labitems table - duplicates in code

[yumikim381]

Dear MIMIV team,
thank you for your wonderful work!
I'd like to ask you something about d_labitems table : some codes have same label, same fluid value, same category,
yet have different codes. Is it safe to assume that those code means the same thing, although the values are different?

For example, there are multiple codes for label "Delete", fluid "Cerebrospinal Fluid" , category "Hematology".

Also, i noticed that some labels are called "Delete". What lab values does it mean? Is there somewhere more description of those lab values that i can reference to?

Thank you and have a nice day!

kind regards,
Yumi
