Sounds good. Probably without the “etc.” So: “Generic unit for indivisible thing”
No worries, they can just be called {PTs}…
Standing for ‘parts’ or ‘patients’?
As for me part can be confused with part of the whole / proportion.
It’s already in Athena.
Could we add Microkatal per Liter to our unit vocabulary? It is unit to measure Lactate dehydrogenase activity
On it.
Dear community!
Here are some units that were lacking during ETL process and which we are planning to add to UCUM vocabulary. Any considerations?
milliliter per kilogram per minute – ml/kg/min
nanogram per kilogram per minute – ng/kg/min
wood unit per square meter – [wood’U]/m2
dyne-second per centimeter to the fifth power per square meter – dyn.s/cm5/m2
million per kilogram –10*6/kg
millivolt – mV
gram per 72 hour – g/(72.h)
kilojoule per mole – kJ/mol
gram per 48 hours – g/(48.h)
unit per 10 to the 10th power cells – U/10*10.{cells}
pack per day – pack/(24.h)
micrometer per second – um/s
picogram per gram of creatinine – pg/g{creat}
nanomole per minute per mg of protein – nmol/min/mg{protein}
cells per 7.5 mililiters – {cells}/(75.10*-1.mL)
femtoliter per nanoliter – fL/nL
unit per kilogram – U/kg{Hb}
unit per 2 hours – U/(2.h)
threshold cycle value – {Ct_value}
milliliter per pound (US) – mL/[lb_us]
millibar – mbar
nanogram per nanogram – ng/ng
free thyroxine index – {FTI%}
milligram per deciliter per 24 hours – mg/dL/(24.h)
picogram per milligram of creatinine – pg/mg{creat}
picomole per hour per microliter – pmol/hr/uL
nanomole per 24 hours per milligram – nmol/(24.h)/mg
milliliter per minute per 1.73 square meter – mL/min/(173.10*-2.m2)
milliliter per millibar – ml/mbar
millibar per centimeter of water – ml/cm [H2O]
millibar per liter – mbar/L
Hi! Do we really need this in OMOP?)
Why not – it is a measure of pulmonary vascular resistance. Used in a number of treatment guidelines for pulmonary arterial hypertension.
The big controversy is Wood Units/m2 versus Wood Units.m2 (slash versus dot)
incredible thank you for information!
This thread has been quiet for a while, but I want to document a few other units that are missing:
We already have /L, /mL, /dL, /uL. These should be added:
- /nL
- /pL
Welcome to the family
@fritzp any particular lab tests associated with these units?
We don’t add every possible option (L, mL, dL, etc.), but rather focus on units that are associated with lab tests.
Hi @zhuk - thanks for your response. At our organization I found that /nL is used frequently for a WBC test (absolute basophil/eosinophil/lymphocyte/monocyte/neutrophil count), and /pL is used for RBC count.
Ideally, we would be able to map to these units directly. But in the absence of a standard unit, would organizations create a non-standard unit or convert results for these tests to a standard unit (/uL)?
Thanks again for your input!
How about billion cells per liter or million per milliliter? After all, the measurement did not happen in a nanoliter, so the unit is as much derived as these would be.
