Introduction:
Many studies, since the 60’s, have endeavoured to establish a relationship between recurrent pregnancy loss (RPL) and acquired thrombophilia, namely lupus anticoagulant (LA), anti-cardiolipin (ACA) and β2-glycoprotein-1 (β2-GP1) antibodies. However, there is still unconvincing evidence to link the two identities (Preston et al, 1996). A meta-analysis of 31 studies (Rey et al, 2003) showed only a modest relationship between them. A high prevalence of RPL among young Malaysian women warranted such a study.

Objective:
To determine the relationship between acquired thrombophilia and RPL in young Malaysian women.

Methodology:
990 RPL-women, aged 20 to 40 years, were investigated for the three immune antibodies by clot-based and ELISA methods. The patients were free of abnormal clinical conditions which could cause RPL.

Results:
4.74% of the patients were positive for one of the three immune-antibodies which coexisted in similar prevalence in the positive-patients.

Conclusions:
The prevalence of LA, ACA and β2-GP1 in Malaysian RPL-women is similar to that of 4-5%, as seen in other studies worldwide. However, our contention is that there is the presence of a yet to be identified causative agent(s) or a combination of numerous factors that is responsible for the RPL, and the 3 immune antibodies being mere “red herrings”.
