I was an at random test with breath a lizer and first blew .02 and after 6 or 8 tries finally blew .052. Is this normal

When it comes to such a low reading, i more likely that the reading will fluctuate. Think of it this way.... think of a scale you'd use to weigh yourself but instead you put 1.5 pounds of apples on it weigh them, then move them around and weigh them again. The amount is so small considering the scale, you get more fluctuation in the readings.

Small fluctuations are not unusual, no....................
