Abstract Background: Approximately 10-15 % of all clinically recognized pregnancies end in miscarriage, the majority of them occur during the first trimester, underlying the cause of the loss. Genetic analysis of fetal tissues has the potential to provide valuable information and is highly recommended in some cases. Around 3-4 years ago, the gold standard for the analysis was the GTG Kayrotype, is well known that around 50 % of the tissue samples received failed to grow in culture. Different molecular techniques are used to improve the quality and the specificity of the study, intending to circumvent the limits of the Karyotype. Results: Karyolite-BoBs™ (KL-BoB™) assay is a recent bead-based suspension, low density array technology with consistent results, probed that is an efficient molecular method to detect aneusomies in early pregnancy losses. Fifty samples from abortions were analyzed in order to probe and give more information about the methodology and analyze if KL-BoBs™ is a good and cost-efficient strategy. We detected 32 % of chromosomal abnormalities, in some of the cases more than one aberration was identified, the array CGH validate the observations. Conclusions: This molecular strategy is a cost-effective sensitive tool in the early pregnancy loss study. © 2015 Pérez-Durán et al.
