Overview
Pregnancy test results in Apple Health record the qualitative outcome of a home urine test for human chorionic gonadotropin, or hCG. The saved value is a result category, not a laboratory hCG concentration or a measure of pregnancy progression.
What are the possible results?
| Code | Result | Interpretation of the saved record |
|---|---|---|
| 1 | Negative | A negative result was recorded |
| 2 | Positive | A positive result was recorded |
| 3 | Indeterminate | An inconclusive result was recorded |
The numbers identify categories. Their average has no clinical meaning, and code 3 is not a stronger result than code 2. A missing row is also different from a recorded negative test.
Why can results differ over time?
The FDA explains that testing too early can produce a negative result despite pregnancy, and following the particular test's instructions affects accuracy. A saved category does not include all details needed to assess timing, sensitivity or technique. Consult the test instructions and a healthcare professional when results remain uncertain.
Serial entries can show a sequence of recorded outcomes. They cannot quantify changing hCG, determine gestational age, assess viability or identify the location of a pregnancy. An apparent negative-to-positive transition is a change in saved results, not a measured rate of hormone increase.
What does recording cadence tell you?
Spacing reflects the tests and entries that were saved. Multiple results on a date may be separate tests or duplicate imports, so inspect provenance and matching intervals before counting. A period of missing entries does not mean that no testing occurred.
A useful display would plot each category against recorded dates with visible gaps and source labels. It would retain indeterminate results rather than merging them into negatives, and avoid a continuous numeric line through category codes.
What can related entries add?
Menstrual-flow start markers may give a recorded timing reference. A pregnancy interval is separate contextual data and is not automatically created or confirmed by this result.
What did the example data show?
No pregnancy-test rows were present in the research window. Result frequencies, repeat-test cadence and transitions could not be measured. No measured figure or hCG range is presented.
What remains unknown?
Brand, sensitivity, sample technique and clinical confirmation are not defined by the category alone. There is no universal category cutoff in hCG units. Treat personal interpretation and follow-up as dependent on the actual test and clinical context rather than on this export's numeric code.
