PGT-A是一種對胚胎進行的基因檢驗，用以辨識染色體數目異常（非整倍體）。
我們的次世代定序技術讓我們能夠分析全部24種染色體。在進行胚胎著床前偵測染色體異常，可在資訊充足的情況下做出決定，並提高懷孕成功率。
獨立研究曾經比較我們的PGT- A檢測與其他實驗室的檢測，關鍵比較如下：
MitoScore是Igenomix研發的粒線體生物標記(mitochondrial biomarker)，讓我們能夠有一個胚胎活力狀態的指標。
MitoScore讓我們能夠選擇著床成功率最高的胚胎，因此較有可能透過IVF / PGT-A得到可能的妊娠結果。*

臨床轉譯的研究是整合mtDNA拷貝數（MitoScore）與PGT-A常規的遺傳分析
偽陽性：胚胎可能會被進行不必要的排除，但機率很小
偽陰性：被診斷為正常的胚胎有可能仍有幾小的機率是異常染色體
2. PGT-A只能檢測胚胎切片，而不是整個胚胎
3. 無法偵測與遺傳物質增減無關的結構異常
4. 染色體增減低於10Mb
5. 鑲嵌程度低（<30%）
6. 單親二體症（UDP）
7. 影響完整染色體組的缺陷（單倍體、三倍體）
