What this test measures
2This section shows the biological marker/agent measured by this diagnostic test. Each marker/agent opens its own page with related conditions. Detailed reference ranges are shown separately in the Reference ranges and concentrations section below, so they are not repeated here.
Reference ranges and concentrations
2These ranges are pulled from the existing EH diagnostic-test reference range tables. They can vary by laboratory, method, age, sex, sample type and clinical situation.

|---|---|---|---|---|---|
| Fetal Heart Rate (Beats Per Minute) | 110 – 160 | Not specified | Not specified | Both | Maternal Tests / Tests of Fetal Well-Being |
| Number of Fetal Accelerations (On CTG) | 2 – 5 | Present | Adult ( > 16y) | Female | Maternal Tests / Tests of Fetal Well-Being |
