If your familiar with Santo Domingo go to the Referencia Labratoria just to the right of clinic abreu on Ave Independencia. Just write on a piece of paper - prueba del VIH....and they should be able to figure out what you want from there - like others said it should be less than $1000 pesos - probably 300-400 is my guess.
I went to this place Monday (8/17/15) and learned the following:
The total bill for HIV, Hepatitis B & C, VDR1 (sifilis), herpes, clamidia, and HPV (papilloma) $10,740 DOP
bill for HIV $375 DOP (Good guess Karl.)
bill for HPV $6,400 DOP
I googled the HPV test to learn that there is no FDA approved test for males. Referencia didn't tell me this when I asked the price, but I wasn't speaking to a test administrator.
