Can you get HIV from using the same sharp objects as someone else?

Like razors and pins, after they used them.

Is it safe if you cleaned their blood off? Can the virus still be on it?

And what other diseases can you get from doing this?

How long can any diseases stay on the object after someone uses it to break their skin?

Also, how accurate is getting blood work done?

1. it is NEVER safe to share sharp objects with an HIV+/ AIDS patient EVER.

2. A Virus , such as HIV, is not a living organism. it is a piece of genetic code that attacks a cell and replicates itself. so, just throw the blood infected instrument away.

3. in this day and age blood work accuracy is about 95% with a 1 in 379000 chance of a false positive ( test coming back HIV+ when the patient doesn't have HIV)

You can contact HIV from sharp objects if the object has been exposed to blood from an HIV positive individual. You can clean the blood off but the virus can still be present on the item. You can also contact Hepatitis B and Hepatitis C from objects that have been exposed to blood.

Blood tests to determine if you are HIV positive are 99.9% accurate.

It is really a bad idea to share razors, toothbrush etc. You could get hepatitis B, C etc or HIV. If you have your own razors etc, there would be no need for to worry about things like this.

The other question seem to whether you trust the laboratory in your area or not. Any laboratory should have accreditation which means their procedures are safe and reliable and they also employ qualified staffs etc. Word of mouth is also very useful in picking the right facility to do the tests. But choices could be limited due to third party contracts etc.

razors yes,,,if they got their blood on it,and you shaved,and had a nick or got nicked with it...could transfer.
virus don't live long outside the body, but pins are like needles...you don't just wipe microorganisms off of something,they would have to be sterilized,boiled.,throw away razors after one uses them.
Don't know what you mean about blood work,but phlebotomist or lab techs,use sterile technique,only,I would be more worried about a tattoo place.
