Any resistor that reads HIGHER than marked value in-circuit is bad. Other parallel paths within the circuit can cause LOWER readings, but not higher.
If I find one that reads lower in-circuit, I look at the schematic to see if there are other components connected that can shift the readings. Non-electrolytic caps and tubes should not effect things (no DC path through them), but other resistors, inductors, and electrolytics (including power supply rails) certainly can.
