LOINC Code 70954-3: Standard process followed for residual renal function assessed in calculating Kt/V [ESRD]
70954-3 is a LOINC code used to identify Standard process followed for residual renal function assessed in calculating Kt/V [ESRD] 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 Standard process followed for residual renal function assessed in calculating Kt/V. 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 Standard process followed for residual renal function assessed in calculating Kt/V. 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: ESRD
What it does not mean
- The code identifies the observation or test, not the actual result.
Key facts
- Standard process followed for residual renal function assessed in calculating Kt/V [ESRD]
- Standard process followed for residual renal function assessed in calculating Kt/V
- Indicates whether the standard process of assessing Residual Renal Function was performed when calculating the Weekly Kt/V. 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.
