一項最新研究業已證實基因芯片分析得出的高水平基因表達特征是可以重復的，能夠在臨床應用中進一步推廣。

基因芯片質量控制(MAQC)研究是由美國食品藥品協會(FDA, Rockville, MD, USA)領導的合作研究。該研究包括來自私立和公立實驗室的137位科學家。Affymetrix(Santa Clara, CA, USA)和其他基因芯片和試劑生產廠商參加了為期2年的初始設計，以驗證基因芯片檢測數據的可重復性。該研究結果報道在2006年9月8日《自然生物技術》之上。
 
Study Determines MicroArray Data Reproducibility
 
A new study has demonstrated that at a high level, gene expression signatures generated by microarrays are repeatable, further advancing the field towards widespread use in clinical applications.

The MicroArray Quality Control (MAQC) study was a collaborative effort led by the U.S. Food and Drug Association (FDA, Rockville, MD, USA). The study included 137 scientists from private and public sector laboratories. Affymetrix (Santa Clara, CA, USA) and other microarray and reagent manufacturers participated in the two-year initiative designed to address the reproducibility of data generated from microarrays. The study’s results were reported in the September 8, 2006, issue of Nature Biotechnology.
