In brief: Not necessary
A negative PPD simply means you don't have a lump at the site of the PPD injection 48-72 prior. This means the skin appears normal.
If there is a raised bump at the site, then depending on your particular risk factors or history, you may be positive. The next step would be a chest x-ray. But, if no bump, then negative.
