It can change. That mild variation is not concerning. There is no reason to monitor this.

All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Talk to the doctor who ordered the tests. Having said that, the variation on your MCV is not a cause for concern. Wish you good health!
