我根据visa interview letter上提供的链接去看体检需要准备什么，在 Medical Examinationz这个网页（https://travel.state.gov/content/travel/en/us-visas/immigrate/the-immigrant-visa-process/interview/interview-prepare/medical-examination.html），我看到体检要求带：
Obtain the following records and bring them to your medical examination:
- Your vaccination immunization records
- Any prior chest x-rays
- Copies of your medical history records
- Your passport, identity card, laissez-passer, or travel document
但是我在 List of U.S. Embassies and Consulates，点击Guangzhou (GUZ)进去后，看到这个说明文件（https://travel.state.gov/content/dam/visas/iv-dv-supplemental/GUZ-Guangzhou.pdf）中要求
- Bring the following items to your medical exam:
- ? Your visa interview letter,
- ? Your passport,
- ? Recently taken passport-sized color photographs (refer to the physicians’ website for instructions), and
- ? A copy of your immunization records.
这2个地方关于体检要带的材料的说明不一致，请问您我应该按照哪个指示去做，谢谢您
