if we are taking reading of NSS without culture it give 0.25 mcfarland. Shall we adjust the suspension to 0.75 to get 0.5 mcfarland value

Yes, the suspension should be adjusted to 0.75 McFarland. Since the reading without culture is 0.25 McFarland, to reach a 0.5 McFarland value, the suspension must be increased by 0.25 McFarland. Adding this to the initial 0.5 McFarland requirement results in a total of 0.75 McFarland.
