unknown generation elisa test performed at 51 days after my last risk

[cuellar]

i performed oral sex on a woman ( very short time contac: 30 seconds)  this has been the only one behaviour risk since that time.I was tested at 51 days with a negative result. the question is :  if i don´t know the kind of generation test it was performed, can i be confident that there's the same 99% ( acording the most post in this forum for newer generation tests )  of probablity that i don´t get hiv ?
p. d : excuse my english , i am from venezuela.

You were never at risk of contracting HIV from going down on a woman. You did put yourself at risk for possible other STDs though.

I dont know if we can post is spanish so i`ll write in both lenguages.

There is no risk in giving oral sex to woman the cdc doesnt even have an stimated risk for it so no test even needed. you are home free, move on,

No hay riesgo en darle sexo oral a una mujer nunca a habido un caso de este tipo documentado, el CDC ni siquiera puede calcular el riesgo teorico, asi que tranquilo amigo ni siquiera necesitabas el test.

Thanks, by your comments, i ask you understand me , i 'm still worried. the point is that i 'm not sure the generation of my elisa test. I ask lab and they said me that the test they performed to me it was 3rd generation but i don't trust a lot them , the reason is that i live in Venezuela and i don't belive that for a lab of resources not very high they could have this  expensive technology ( 3rd generation test) . In the case the test was practiced to me wasn't 3rd generation but 2nd generation the probably of 95 % still remain? thanks .

creo que hay un medico en el foro que es argentino y responde preguntas en espanol,  creo lo que sucede en estos paises respecto al conservatismo respecto al periodo ventana de tres meses y no de seis se relaciona con la organizacion existente en USA  respecto a las estadisticas y los controles es decir me imagino que alla llevan una especie de historia medica para cada paciente y realizan las pruebas a las 6 semanas y luego a los tres meses y posteriormente calculan porcentajes con esos datos y de ahi sale lo del 99% a las seis semanas, supongo que aqui en estos paises esos datos no son llevados de manera muy organizada y es por eso que son tan rigidos respecto al periodo de tres meses, menos nada. si uno busca paginas web en espanol ninguna le va a decir que el test a las 6 semanas es bastante confiable y me imagino que es por estas razones . Gracias nuevamente

If they said 3rd gen then thats what they use, why would they lie? You have real base as to not believe them.

The 95% its for all tests even for 1st generation, and 3rd generation test are not high expensive technology, most rapid 3rd generation test have a price from $1 to 5$, so if they said 3rd generation then that is it. the issue of our southamerican goverments to say the 3 months is the only conclusive test is becouse they just copy the CDC guidlines since there is not a lot of money here to research,

El 95% es para todos los tests, incluso los de 1ra generacion, los test de tercera y cuarta generacion no son muy caros la mayoria cuesta entre 1 y 5 dolares, el problema con el periodo ventana es que la mayoria de nuestros paises (sudamericanos) no tienen recursos para hacer muchos estudios talvez solo Brasil, y lo que hacen es copiar textualmente las recomendaciones de la CDC de USA.

ELISA, the most commonly performed diagnostic test in developing countries like India, to detect HIV Antibodies (Ab) is classified on the basis of Antigens (Ag) used.
1st Generation - used infected viral cell lysate as antigen.
2nd Generation - used glycopeptides (recombinant antigens)
3rd Generation - synthetic peptides are used as antigens.
4th Generation, are the newer tests for simultaneous detection of p24 Ag (HIV-1 Ag) and HIV-1/HIV-2Ab.
HIV tests utilizing Recombinant antigens would be 2nd Generation.
Abbot AxSYM test is a 3rd Generation test.

I may be wrong, but somebody posted here few times back about the comparison between the tests:
"In general, a fourth generation test will detect HIV about a week earlier than a third generation test (by detecting the P24 antigen) and a third generation test will detect HIV antibodies about a week earlier than a first generation test.  A second generation test (such as used by LabCorp) will detect HIV antobodies somewhere between the first the third generation tests."

i am a little paranoid, also i put in contact my face with her vagin,  before i wiped (dry) her vagin with a towel to reduce the vaginal fluids . please answer me

Again, never at risk for HIV. You may want to visit the STD community.

[worried826]

You were never at risk, that isnt going to change, plus you have a 7 week negative test. Move on already.
