Your hepatitis B virus surface antigen result is 2.38, which is below the normal threshold of 10 IU/ml, indicating you're likely not infected. So, you don't need to worry much about hepatitis B. If you want further reassurance, you can take a quick express test for fast results. The risk of infection from blood on your skin depends on factors like the amount of blood, any existing cuts, and how quickly you clean it off. Usually, brief contact with blood on the skin doesn't pose a high risk of hepatitis B infection. Overall, your levels are normal, so you can relax. But if you're still concerned, an express test can provide peace of mind.
