如果你有一个tattoo, you can only donate blood if you meet certain criteria. A good rule of thumb is that you may not be able to give blood if your tattoo is less than 3 months old.

这适用于穿孔nd all other nonmedical injections on your body, too.

Introducing ink, metal, or any other foreign material into your body affects your immune system and may expose you to harmful viruses. This can affect what’s in your bloodstream, especially if you got your tattoo somewhere that isn’t regulated or doesn’t follow safe practices.

如果您的血液受到损害的机会，捐赠中心将无法使用它。继续阅读以了解资格标准，在哪里找到捐赠中心等等。

Giving blood在最近得到一个纹身可以是危险的。Though uncommon, an unclean tattoo needle can carry a number of bloodborne viruses, such as:

有新纹身的人have traditionally been advised to wait a year before giving blood in order to reduce their risk of unknowingly transmitting these viruses.

However, in April 2020, the Food and Drug Administration (FDA) updated their recommendations and proposed a recommended deferral period of 3 months. If you’ve contracted a bloodborne illness, detectable antibodies will likely appear during this 3-month period.

That said, you may be able to donate blood in under 3 months if you got your tattoo at a state-regulated tattoo shop. State-regulated shops are routinely monitored for safe and sterile tattooing practices, so the risk of infection is low.

有些州选择了不受监管的，因此不要犹豫问你的首选艺术家事先关于他们的资格。

It’s best to work with licensed artists who tattoo in state-regulated shops. Oftentimes, their certifications are prominently displayed on the shop walls.

Getting a tattoo at a tattoo shop that’s not state-regulated makes you ineligible to donate blood for 3 months.

不需要受到纹身商店的国家包括：

  • 亚利桑那
  • Idaho
  • Maryland
  • 内华达州，虽然state laws正在开发中
  • 纽约虽然state laws正在开发中
  • Pennsylvania
  • 犹他州
  • Wyoming

但是，这些国家内部的一些城市或县可能会在地方一级规范纹身店。

国家规范的纹身店需要满足某些安全和健康标准，以避免将客户的血液纳入血腥的条件。在未调节纹身店内无法保证这些标准。

You often can’t donate blood for 3 months after getting apiercing, either.

Like tattoos, piercings can introduce foreign material and pathogens into your body. Hepatitis B, hepatitis C, and HIV can be contracted through blood contaminated by a piercing.

There’s a catch to this rule, too.

虽然许多国家规范提供刺穿服务的设施，但有关于基于所用设备的资格的具体规则。

如果在状态监管设施用单用枪或针头进行穿孔，则应该能够捐献血液。

如果枪可重复使用 - 或者你不是绝对确定它是单用的 - 你不应该在3个月过来之前给任何血液。

以某种方式影响你血液的条件可能会让你没有资格捐献血液。
