Soil changes over time, and sandy soil changes rapidly. Last years test would be wrong on amended soil. PH drops to the original level, nitrogen and potash is leached out of sandy soil, only phosphorus tends to stick around, and even that is not guaranteed. I laid out a woods plot near jarratt (lil' north of emporia) this spring that came back at a pH of 4.2 (terrible) and needed 260 lbs (A LOT) of phosphorus/acre. That's the closest I've ever been to SE VA for food plots. The test will tell you what you need to know.
