Community medical question

Assalamualaikum Doctor, meri mother ko uric acid ka issue hai. Unhein joints me dard hota hai (especially pairon/ghutnon me) aur kabhi kabhi swelling bhi hoti hai. Unhon ne pehle Zaloric (allopurinol) medicine use ki hai. Abhi recent uric acid test nahi karwaya. Kindly guide karein ke kya test karwana chahiye aur kya woh ye medicine continue karein ya change karein. Diet ke hawalay se bhi rehnumai faraham karein. Shukriya.
