LOINC Code 70964-2: Kt/V.Peritoneal Dialysis [Watson]
70964-2 is a LOINC code used to identify Kt/V.Peritoneal Dialysis [Watson] in laboratory and clinical observation data. You may see this code in lab systems, lab reports, EHR exports, interoperability feeds, or other structured clinical data exchanges. LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component Kt/V.Peritoneal Dialysis. It is commonly used with the system or sample type ^Patient.
What is this code?
LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component Kt/V.Peritoneal Dialysis. It is commonly used with the system or sample type ^Patient.
When is it used?
- Used in lab systems, EHRs, and clinical data exchange.
- May identify a test, observation, survey item, or clinical document request rather than a diagnosis.
- Status: TRIAL
- Order vs observation: Observation
- Method: Watson
What it does not mean
- The code identifies the observation or test, not the actual result.
Key facts
- Kt/V.Peritoneal Dialysis [Watson]
- Kt/V.Peritoneal Dialysis
- Indicates the Kt/V urea (dialysate and urine clearance) at the time the Kt/V PD adequacy measurement was performed by Watson Method. K (clearance) multiplied by t (time) is a volume (since mL/min x min = mL, or L/hr x hr = L), and (K x t) can be thought of as the mL or L of fluid (blood in this case) cleared of urea (or any other solute) during the course of a single treatment. V also is a volume, expressed in mL or L. So the ratio of K x t / V is a so-called "dimensionless ratio" and can be thought of as a multiple of the volume of plasma cleared of urea divided by the distribution volume of urea. When Kt/V = 1.0, a volume of blood equal to the distribution volume of urea has been completely cleared of urea.
