What is order of draw Cultural Citrate Plan Heprin EDTA Floride

Question

Accepted Answer

The order of draw refers to the sequence in which blood collection tubes should be drawn to prevent cross-contamination between different additives in the tubes. Here's the typical order of draw for the tubes you mentioned:

1. Blood Cultures (if ordered)

Tube color: Typically, yellow or culture bottles

Purpose: For microbiological cultures (bacteria or fungi), collected first to avoid contamination from other tube additives.

2. Citrate Tube (Coagulation studies)

Tube color: Light blue (Sodium Citrate)

Purpose: Used for clotting tests like PT, aPTT, and INR. Citrate acts as an anticoagulant to preserve the blood for coagulation testing. It's drawn second to avoid contamination from other additives.

3. Serum Tube (Plan)

Tube color: Red top (no additive) or SST (Serum Separator Tube, with gel)

Purpose: For serum tests like chemistry panels or drug levels. If you're using a red top tube with no gel, it’s drawn after the citrate tube to avoid contamination with anticoagulants.

4. Heparin Tube

Tube color: Green (Heparin, sodium, lithium, or ammonium)

Purpose: For plasma tests such as chemistry tests or stat testing. Heparin prevents clotting by inhibiting thrombin. It's drawn after serum tubes to prevent contamination.

5. EDTA Tube

Tube color: Lavender or Purple (EDTA)

Purpose: For hematology tests like CBC and blood counts. EDTA is a strong anticoagulant, and it’s drawn last in order to avoid contaminating the blood sample with clotting agents from the previous tubes.

6. Fluoride/Oxalate Tube

Tube color: Gray (Oxalate/Fluoride)

Purpose: Typically used for glucose testing. This tube contains potassium oxalate and sodium fluoride, which preserve glucose and prevent glycolysis. It is drawn last to avoid interference from other additives.

Summary of the Correct Order of Draw:

1. Blood Cultures

2. Citrate (Light Blue - Coagulation studies)

3. Serum Tube (Red or SST)

4. Heparin (Green)

5. EDTA (Lavender)

6. Fluoride/Oxalate (Gray)

Following the correct order of draw ensures accurate results by preventing contamination from the additives in the tubes.

Accepted Answer

The current CLSI guideline for glass and plastic tubes order of draw is as follows: blood culture tubes; sodium citrate tubes; serum tubes with and without clot activator and with or without gel separator; heparin tubes with or without gel separator; EDTA tubes; acid citrate dextrose containing tubes; and glycolytic

Accepted Answer

Blood culture tube or bottle. Sodium citrate tube (eg, blue closure) Serum tubes, including those with clot activator and gels (eg, red, red-speckled, gold closures)

Accepted Answer

The order of drow designed to eliminate the possibility of cross contamination that may result in erroneous results.

Accepted Answer

If you doing blood culture then need heparin.

Accepted Answer

The order of draw avoid is cross contamination, draw and collected in tube in a specific order,1.blood culture and vails
