Erythrocyte sedimentation rate

Erythrocyte sedimentation rate (lab table).

Name in the dataset esr
Type lab
Stored in lab_data.csv
Stamped by Hospital records clock
Unit mm/hr

Description

Single resolution; no heaping in the whole-number screen.

Its time is the lab system's result time: see Blood gas result time and Central lab result time.

Measurement space

-0.500.5true minus recorded (mm/hr)density

A vertical slice through the measurement space: how the true value is spread around any one recorded value. Its shape is uniform.

Time

Its time side is still to be described.

Value

Model kind uniform: single resolution; uniform over the rounding interval
Resolution 1 mm/hr, nearest
Native step 1 mm/hr
Anchor nearest (convention)

In this release

How wide the true-value distribution is, record by record, over 164 of 177 records (every lab row of 600 random cases) that have one. Computed with the pinned model, aggregates only.

Median p10 to p90
Standard deviation 0.289 mm/hr 0.289 to 0.289 mm/hr
95% interval width 0.95 mm/hr 0.95 to 0.95 mm/hr
Mean minus recorded 0 mm/hr 0 to 0 mm/hr

Anchor

Laboratory results rounded to the last reported digit; at most half the last digit. See what an anchor is and every variable's anchor.

Observations

Observation Status Summary
Three lab analytes stop at a reporting limit likely Lactate is capped at 15.0 mmol/L, aPTT at 400.0 s, and ESR does not go below 2 mm/h: the values at the limit stand for "this or beyond", not for the number itself.

Figures

Histogram of the recorded values of esr.
Recorded values in the release: 1,415 records, median 37 mm/hr; 6 outside the 0.5–99.5th percentiles are not shown.
