Kidney Function Schedule Calculator
Build a twelve-month kidney monitoring calendar from eGFR, urine ACR, stability, clinician-selected laboratory frequency, urine-test frequency, blood-pressure checks, and medication-review timing.
Twelve-month monitoring calendar
Blood, urine, pressure, and medication-review events across one year
Each evidence stream uses its own symbol around the calendar wheel, exposing overloaded months and long gaps while keeping conditional instability review separate.
Month-by-month evidence plan
What is scheduled and why
The ledger lists every calendar month, the planned evidence streams, current context, and any unfilled review gap.
| Month | Blood test | Urine ACR | BP review | Medication review | Calendar note |

Calendar setup
Enter clinician-selected frequencies before choosing convenient dates
- Record current eGFR and urine ACR for context.
- Use frequencies set for the actual diagnosis and treatment plan.
- Choose the month in which the planning year begins.
- Keep medication and blood-pressure reviews distinct from laboratory tests.
- Add earlier checks only when the clinical plan or an instability trigger calls for them.
Evidence timing
A calendar can reveal gaps that an annual count hides
Four blood tests in one month do not provide quarterly surveillance. The wheel therefore shows spacing, coincidence, and the longest gap rather than only total counts.
The page does not derive a medical schedule from the colored risk cell. User-entered clinician-planned frequencies remain authoritative.
Calendar allocation
Distribute each evidence stream independently over twelve months
Each annual frequency is converted to evenly spaced month indices from the chosen start month. Events can coincide when a combined review is efficient. Instability creates an early conditional check without silently changing all future cadence.

Calendar quality
Three ways an annual plan can fail operationally
Counts, spacing, and ownership all matter.
Clustering
—Too many events in one month may leave a long unobserved interval elsewhere.
Missing evidence stream
—Blood, urine, pressure, and medication review answer different questions.
No trigger pathway
—Acute illness, unstable creatinine, or a treatment change may require an earlier clinician-directed review.
Decision takeaway: A usable schedule identifies both routine dates and who responds when the routine no longer fits.
Applied decisions
How identical annual counts produce different coverage
Even quarterly laboratory plan
Four blood tests are distributed every three months.
What the result clarifies: The wheel shows consistent spacing and coordinated medication reviews.
New instability flag
The routine plan is unchanged but a recent unstable result is entered.
What the result clarifies: An early conditional checkpoint appears without rewriting the whole year.

Scope and limitations
This calendar does not prescribe test frequency or replace clinician instructions. Urgent symptoms or acute changes should not wait for the next scheduled month. Pregnancy, dialysis, transplant, acute kidney injury, and complex medication changes require dedicated plans.
Kidney Function Schedule Calculator | Twelve-Month Test and Review Calendar FAQ
Does the risk cell choose the test frequency?
No. Frequencies are explicitly entered from the clinical plan; the cell is context only.
Why combine blood and urine in some months?
Coordinated collection can support a fuller review, but separate timing may also be appropriate.
Can blood pressure be reviewed more than monthly?
Yes. The annual count can exceed twelve; the wheel summarizes it as monthly coverage while the table flags repeated reviews.
What does the instability flag do?
It adds an early conditional review message and does not prescribe the exact test or treatment.
