Description

A yellow-top Vacutainer is a type of blood collection tube used primarily for blood culture and sometimes for serum separation, depending on the exact additive and brand. There are two common types of yellow-top tubes, and it’s important to distinguish between them.

A yellow top Vacutainer is a blood collection tube containing SPS (sodium polyanethol sulfonate) or ACD (acid‑citrate‑dextrose) as additive, used to preserve whole blood for microbiology, culture, DNA or HLA tests. tsd.co.ke+3londonphlebotomytraining.co.uk+3en.wikipedia.org+3

(Less common, usually gold top is preferred for this role)

| Additive | Clot activator + gel for serum separation |
| Purpose | Serum collection for chemistry, immunology, and serology testing |
| Not Typically Yellow | These tubes are more often gold-top, but some systems label them as yellow |

✅ General Features of Yellow-Top Tubes (Depending on Type):

• Sterile: Especially important for blood culture tubes

• Color Code: Universal color coding helps lab personnel quickly identify the correct tube

• Vacuum Sealed: Ensures correct blood draw volume

• Labeling Area: For patient and sample identification

• Cap Type: May be flip-top or rubber stopper

⚠️ Important Notes:

• DO NOT confuse SPS yellow-tops with gel separator yellow/gold-tops

• Blood culture tubes must be collected before any antibiotic therapy begins

• In blood culture collection, aerobic bottle is drawn before anaerobic in most protocols

Yellow top Vacutainers have different uses depending on the additive they contain. There are two main types:

🔶 1. Yellow Top with SPS (Sodium Polyanethol Sulfonate)

• Primary Use:

  • Blood cultures
