Ekawong P, Wiwanitkit V. Weakly positive urine pregnancy diagnostic test rate: A study
on laboratory incidence. Chula Med J 2006 Dec; 50(12): 863 - 7
Urine pregnancy test is currently an easily available diagnostic test. Here,
the authors performed a study on laboratory-measured weakly positive
pregnancy rates in a tertiary hospital in Thailand.
The data from laboratory records of the female patients who got diagnostic
urine pregnancy test at Division of Laboratory Medicine, King Chulalongkorn
Memorial Hospital, Bangkok Thailand from June 2004 to August 2005
There were 3,326 laboratory records reviewed in this study. From
the total 3,326 records, 19 were weakly positive, giving the incidence
rate equals to 0.57 %.
Less than 1 % of the analyses gave the weakly positive result.
The clinical implication of these cases needed further studies to verify.
