Overview | ||
|---|---|---|
| Department | Point of Care Testing (POCT) | |
| Test Code | N/A | |
| Synonyms | BhCG Urine (POCT)
Urine hGC (POCT) | |
| Availability | Disposable Pregnancy Urine testing devices are available at both Taranaki Base and Hawera Hospital in select accredited departments (ED, Theatres, Day ward, endoscopy and surgical outpatients) | |
| Turnaround Time | 5 minutes from the time the urine has been added to the testing well on the device | |
| Stability – Add test | N/A | |
Specimen Requirements | ||
| Specimen | Urine | |
| Preferred | Fresh urine collected in a clean dry pottle/container.
Random urine collected anytime during the day is suitable but a first morning urine will contain the highest concentration of hCG. | |
| Acceptable | Specimens that have been stored in the refrigerator (2-8°C ) for up to 48 hrs. | |
| Minimum Volume | 1 ml | |
| Specimen Collection and Transportation | Urine collected in a clean dry pottle/container.
if being tested straight away sample can be ambient (8-24°C), If longer than sample should be chilled (2-8°C) for up to 48 hrs. | |
Test Information | ||
| Test Method | Lateral flow immunoassay (TestPack +plus OBC hCG urine, Abbott) | |
| Unit of Measurement | mIU/L | |
| Reference Intervals | A positive result usually indicates urine hCG levels of >25 mIU/L | |
| Uncertainty of measurement | N/A | |
| Additional Information | A positive test indicates that there is detectable hCG in the urine specimen, most likely to be due to pregnancy. Tests usually become positive when the hCG concentration reaches 25IU/L.
If there is a high clinical suspicion of pregnancy but the urine test is negative, either send a blood sample to the lab for serum hCG measurement or repeat the urine pregnancy test in 2-3 days. False positive urine pregnancy tests are rare, but the result can be confirmed with serum hCG measurement. If the urine/serum hCG is measurable but there is no evidence of pregnancy, consider whether there is an alternative source of hCG production (for example, from an hCG-secreting tumour). | |
Comments | ||
| Quick user guides for testing should be available near the testing kits.
All procedures, worksheets and competency checklist for sign-off are available on the intranet to all Health NZ Staff. This test is covered under the current IANZ Laboratory accreditation. |
