Can blood be donated elsewhere for my use at UCSF?
你可以在你的社区血库献血,供你在加州大学旧金山分校使用. However, 进行抽血的血库需要额外的时间和潜在的处理和转移费用. 向当地血库咨询他们的政策和指导方针. 您可以确认收到其他地方抽取的血液并通过拨打血液可用线转移到UCSF供您使用, (888) 226-8806.
Can blood be transfused immediately after donation?
No, the donation needs to be processed and tested. This takes three working days from the date of donation.
How long does it take to donate?
献血过程开始后需要30分钟. The actual blood donation takes five to 10 minutes. Platelet donation takes two hours, once the process begins.
There is very little discomfort in donating. 试试我们的捏血测试,感受一下献血的感觉:
- Bend your elbow slightly.
- Grab a 1-inch bit of skin on the inside of the bend.
- Pinch it lightly between your thumb and forefinger.
You probably will not. 通常,捐献之前、期间和之后都会采取预防措施,以确保您的安全. 在整个捐赠过程中,您将被监控是否有任何头晕或头晕的迹象. 所有捐款者在捐款后都要坐在座位上休息并吃点点心.
是的,建议在捐献后4小时内吃一顿低脂肪的饭. 在您捐赠之前和之后,茶点也可用.
在捐献之前,要进行血红蛋白测试,并从每个潜在捐赠者的手指上采集血液样本. Anemia is not always a permanent condition, so unless you are under a physician's care for anemia, you will be a suitable donor.
Are diabetics acceptable donors?
Diabetics must meet a certain hematocrit level, are under the supervision of a physician, and have stable blood sugar levels. 糖尿病患者注射胰岛素或其他药物时必须使用一次性注射器.
Will aspirin affect my blood donation?
阿司匹林的化学成分会损害血小板的功能, 堵塞血管渗漏以防止出血的血液成分, to function properly. 如果血小板献血者服用过任何含有阿司匹林的产品,他们必须在72小时内停止捐献.
How long does it take my body to replace blood I donated?
身体会立即恢复捐献的血液. Fluid stored in the tissues returns to the blood stream. Red blood cell production speeds up. A donor's blood volume is restored within a few hours. Red blood cells replace themselves more slowly, but are restored within the interval between donations.
What is the shelf life of blood?
患者血亲的血液保存期限为28天. A non-blood relative's blood has a shelf life of 35 days.
为什么血亲献血的保存期较短(28天), as opposed to non-blood relatives (35 days)?
Donations from blood relatives must be irradiated before use. Irradiation shortens the shelf life by seven days.
辐照可以预防移植物抗宿主病(GVHD). GVHD是一种供者的白细胞攻击或“排斥”患者组织的疾病,因为供者的白细胞将患者的细胞识别为“外来细胞”.辐照可以防止捐献者献血中的白细胞攻击病人的组织, but leaves the rest of the blood (red blood cells, platelets, plasma, etc.) intact.
What is the shelf life of platelets?
Platelets have a shelf life of five days.
许多献血中心对自体献血或指定献血收费, with payment due at the time of donation. UCSF applies all charges towards the patient's hospital bill.
对使用献血中心的费用和账单有疑问的患者应:
- 查询特定献血中心的收费和计费政策.
- 向病人的保险公司查询他们的费用覆盖范围.
是否有其他捐赠者感染艾滋病毒或其他感染的风险增加, as a result, are also excluded from donating blood?
静脉注射药物滥用者被排除在献血之外,因为他们有艾滋病毒的流行率, HBV, HCV和HTLV比一般人群高得多. 接受过动物组织或器官移植的人被排除在献血之外,因为传播动物捐赠者所携带的未知或新出现的病原体的风险在很大程度上仍然未知. 最近去过某些国家或在某些国家居住的人可能被排除在外,因为他们有传播疟疾或变异型克雅氏病等病原体的风险。. 以金钱或毒品换取性行为的人也被排除在外,因为他们传播艾滋病毒和其他血液传播感染的风险更高.
Why are some people, such as heterosexuals with multiple partners, 允许献血,尽管这增加了传播艾滋病毒和肝炎的风险?
Current scientific data from the U.S. 美国疾病控制与预防中心(CDC)指出, as a group, 与其他男性发生性行为的男性比处于其他风险类别的个人传播传染病或艾滋病毒的风险更高. 而统计数据显示,年轻异性恋女性的感染率正在上升, 他们的总体艾滋病毒感染率仍然远低于男男性行为者. For information on HIV-related statistics and trends, go to CDC's HIV/AIDS Statistics and Surveillance Web page.
