其实不接触猫粪便，吃东西前洗手就好了

如果你以前养过outdoor猫， 或一直养猫（不知一只）mostlikely you were already infected， 弓形虫对成人无害，一旦感染人就会产生抗体， 终生免疫， 包括胎儿。 一般vet and OBG won't ask you to test your cats, cause it doesn't realy tell anything.也许只差一个数，你今天就是nagative,明天变一点， 高于range你的猫就是positive.
其实不接触猫粪便，吃东西前洗手就好了。 还有，if you have an outdoor cat or you have seen other cats in yr backyard, you should stop doing yardwork during yr pregnancy.
if you realy want to 100% sure, ask yr vet to find your a 弓形虫 and eat it before you trying to get pregnant. ;-) just joking

Don't get rid of your cat(s).
