I had two needle stick injuries during my medical training, both of patients i cross checked at that time had negative reports.I also used syringes to flush out debris and stuck food from impacted third molar, last used on 20th March . I brought these syringes from my training hospital and as far as i can remember were new. After 1 year of last needle stick i went for general blood tests which had hiv 1/2 rapid test(in march 2019). It came back reactive. After which i tested in government ART center with WHO serial testing algorithm which had all tests negative. After one week went for tridot test again negative. Then CMIA test again negative. After 35 days of tridot again cmia and tridot negative. Finally after 75 days of 1st test Cmia test again negative. Now my question is that can the 1st test be detecting some subtype which is not detected by further tests which i underwent? I am very much anxious about this as i am about to get married.
On 21 march 2019 Hiv 1/2 Rapid ab- reactive
23 march 2019 WHO 3 test algorithm(ART centre) - negative
1st April Tridot-negative
2nd April Tridot-negative
2nd April Cmia antigen antibody(dr lal lab) - negative
6th may cmia(drlal lal) and tridot- negative
8 june cmia(different lab) - negative
Can there be some subtype which other tests are not able to detect and is detected by first test?
Can CMIA antigen and antibody test detect all subtypes of hiv?
If the two patients in question were HIV negative then obviously that first reactive result was a false positive. You can't get HIV from someone that doesn't have it.
Clearly this has been weighing way too heavily on your mind and you are overdue for counseling to help you overcome this problem. Your multiple negative tests prove without a doubt that you do not have HIV. For you to completely shut down your life for over two years about this is very unhealthy.
If this is how you will react to accidents in your chosen profession, you need to seriously consider changing careers. Patients depend on you when they are at their most vulnerable and if you cannot do your job without falling down an anxiety spiral of your own making which causes you to completely shut down your life in this manner, then this is not the right job for you. Get counseling, find a new career, and move on with your life.
