What color of vacutainer top do you use for vancomycin level?

For vancomycin level testing, a serum sample is typically collected using a red-top or gold-top vacutainer. The red-top contains no additives, while the gold-top contains a gel separator that allows for serum separation after centrifugation. It's important to ensure the sample is properly processed to obtain accurate results. Always check with your specific laboratory guidelines for any updates or variations.
