Can leg pain and burning sensations affect an HIV test?

Hi doctor,

I had tested with a fourth-generation duo rapid test kit at home after eight years of sexual exposure with a female sex worker, and it came back negative. The description of the test kit is as follows: common substances such as pain and fever medication, as well as blood components, may affect the performance of the 4th-generation antigen or antibody rapid test. So when I was tested with that kit at that time, I had no fever, but I had pain in my legs and a burning sensation in my hands and feet. So, do these symptoms affect the test result? Is this a false negative result? Kindly help me.

Thank you.

Hi doctor,

Thank you for your answer.

While I was tested five months back, I took multivitamin tablets, B12 injection, Tryptomer, and Pregabalyn M 75 mg tablet for anxiety. I had tested my vitamin B12 level before one month of the HIV test; the B12 level was 2000 pg/mL. So does this affect my test result? Also, I was stressed and anxious for the last year before testing, and the result was not enough antibodies to detect HIV infection. Kindly answer.

Thank you.

Hi doctor,

Thank you for the reply.

I have attached the photo of the test kit, which is 100 % conclusive. However, while testing with the test kit, I accidentally opened the test device and came in contact with the kit device antigens (pinkish liquid) with a pricked finger; so, will these HIV antigens in the rapid test cause infection? Do I get HIV from coming into contact with antigens (gp41) of the test device? I am very scared. Also, I have continuous pain in my legs, a burning sensation in my legs, hands, and buttocks, and sometimes shifts to my knees.

Are these arthritis symptoms? Or have I developed peripheral neuropathy? Or other diseases which may have symptoms like continuous pain in my legs, burning sensation in hands, buttocks, knees, and on my back, which the HIV antibody test kits can not detect? For the past year, I have been under stress and fear of HIV. So kindly explain in brief. Is this test 100 % reliable, or do I need more tests? Do the rapid tests detect HIV infection after eight years of exposure?

Thank you.

Hi doctor,

Thank you for your answer.

Do HIV 4th-generation rapid tests detect HIV infection after eight years of exposure? I tested CBC four months before the HIV test, and the report showed that lymphocytes were 15 %, and after the test, the lymphocytes were 20 %. Do low lymphocytes affect the test result?

On my left-hand thumb, I have two vertical grey lines, which I read somewhere is a symptom of HIV. And also in the last eight years, I have had armpit lumps three to four times; all these symptoms scared me, and I thought the result was a false negative. Do I need more testing?

Thank you.
