Effectiveness of Pregnancy Tests as an Assessment Tool to Identify Continuing Pregnancy
Effectiveness of Pregnancy Tests as an Assessment Tool to Identify Continuing Pregnancy
This randomized study will examine the effectiveness of two types of pregnancy tests (a
 semi-quantitative test and a high sensitivity test) to identify continuing pregnancy at home
 at various time points after early medical abortion. The first test a semi-quantitative panel
 test marketed under the brand name dBest (AmeriTek, Seattle WA, USA). This urine-based,
 one-step kit has been used in two previous studies in Vietnam (12, 13). The second test is a
 locally available urine dipstick (Quickstick one-step hCG Pregnancy Test, Phamatech, San
 Diego, CA, USA).

 1. The investigators hypothesize that 99% of the SQPT and 35% of the HSPT will correctly
 identify ongoing pregnancy at day 14.

 2. The investigators hypothesize that 99% of the SQPT and 25% of the HSPT will correctly
 identify ongoing pregnancy at day 7.

 3. The investigators hypothesize that 75% of the SQPT and 10% of the HSPT will correctly
 identify ongoing pregnancy at day 4.
