try to go to big companies like emcor, sm (foundation), and others since they have employees who regularly donate blood and u can borrow their card.. or ask for help from them approach the manager..
My helper got dengue the other month. Her doctor from San Pedro Hospital suggested this Chinese medicine so that platelets will go up. She was supposed to be transfused with blood but thanks to this medicine, she's ok now. The name is Tongren NIUHUANG Qingxin Wan. You can buy this at Suy Hoo chinese pharmacy fronting Gaisano Mall Bajada. God bless!
