@Poster, guess your new employers are trying to 'do Ijebu'. Usually the employer gives the new employee a letter to the company's designated hospital which already knows the kind of test the company requires to be carried out on the new entrant. Yours is just to submit yourself for the test, what test is going to be carried out and the payment is none of your businesss. The hospital sends the result directly to your employer and you may not know the result of the test conducted on you!!! :oThat is Naija for you o, my brother. However, these days, some doctors may tell you the kind of tests (usually, HIV 1 and 2 tests are a main feature), you may object to this but then the doctor will indicated in the result that you did not submit yourself to such and such type of test (which means, , your guess is as good as mine).
Some of the conditions tested for include HIV 1 & 2, Tuberculousis (through chest xray), a woman's tummy is also scanned (for whatever purpose I don't know), (the thing wey ladies eye dey see self

), they'll press your bobbies testing for lumps

, infact your are lucky that you are a man.
It's disappoint though, that you have to pay for these tests. Well, I wish you all the best.
