If your variable is x and you suspect it is lognormal, then ln(x) should be
normal.
You could check this by looking at a histogram of ln(x) with a normal
distribution overlaid. Check skewness and kurtosis. Have a look at a Q-Q
plot. Run a Kolmogorov-Smirnov test or Shapiro-Wilks test.
The usual sort of stuff you would do when checking normality of a variable.

Subject: st: goodness-of-fit test for lognormal distribution
Dear all,
How can I test whether a variable is lognormally distributed?
