Yesterday, I have given blood for urea test.The lab person had the unchanged glove. Touched by arm from where he drew my blood also rubbed a cotton on the site from where he inserted a new needle syringe with the unchanged glove. He also might touched the needle. At last put a small round band aid on the site of inserted needle with the unchanged glove. I am very much anxious about cross infection of blood borne diseases like HIV, HEPATITIS A,B,C ?? Can I get any diseases from above mentioned test .please reply me at the earliest.
