The amps will never be 1.5 ml, i can see why you think this when you read the vial but look closer or draw the test into a syringe, you will soon see it will be 1ml or maby just under. Never 1.5ml vials.
The 1ml marking will have a line around the vial and the fill line is the line higher but when you draw it you will only get 1ml. Hope this is of help
