## Types of Phlebotomy Collection Tubes

Phlebotomy collection tubes come in various types, each designed for specific tests and purposes. Understanding these types will help ensure optimal sample integrity and test accuracy.

### 1. **EDTA Tubes (Lavender Top)**

– **Uses:** Used primarily for hematology tests like complete blood counts⁢ (CBC).
– **Additive:** Ethylenediaminetetraacetic acid (EDTA) acts as an anticoagulant by binding calcium ions.

### 2. **Citrate Tubes (Light Blue Top)**

– **Uses:**⁣ Mainly for coagulation studies, including PT, APTT tests.
– **Additive:** Sodium citrate, which also ‍acts as an anticoagulant.

###⁤ 3. **Serum ⁤Separator Tubes (Gold or Tiger Top)**

– **Uses:** Used for⁣ biochemical tests; allows serum to ⁤be separated easily.
-​ **Additive:** Clot activator ​with a gel separator.

### 4. **Heparin Tubes (Green Top)**

– **Uses:** Ideal for tests requiring plasma, like certain chemistry tests.
– **Additive:** Heparin, which inhibits thrombin.

### 5. **Sodium Fluoride Tubes (Gray Top)**

– **Uses:** Common⁤ for glucose and lactic acid tests due to its preservation qualities.
– **Additive:** Sodium fluoride and potassium oxalate; the former inhibits glycolysis.

### 6. **Plain Tubes (Red Top)**

– **Uses:** Used for serology and other tests where serum is‍ needed without anticoagulants.
– **Additive:** No additives, allowing blood to clot naturally.

###​ Summary Table of Phlebotomy Collection Tubes

Tube Color	Additive	Common Uses
Lavender	EDTA	Hematology (CBC)
Light Blue	Sodium Citrate	Coagulation (PT, APTT)
Gold/Tiger	Clot Activator + Gel Separator	Biochemical Tests
Green	Heparin	Plasma Tests
Gray	Sodium Fluoride + Potassium Oxalate	Glucose, Lactic Acid
Red	No Additives	Serology

## Uses of Phlebotomy Collection Tubes

Each type of collection tube is engineered for particular testing ‌scenarios. ⁢Here’s a deeper insight into their practical uses:

– **Hematology Tests:** Lavender top tubes containing EDTA are crucial for complete blood counts (CBC) since they maintain the ​shape and count of blood cells.

– **Coagulation ⁤Studies:** Light blue tubes are indispensable for tests related to blood clotting, ensuring accurate assessments of bleeding disorders.

– ​**Biochemical Tests:**⁤ Gold or tiger top tubes are preferred in clinical chemistry due⁣ to their⁤ efficient separation of‌ serum.

– **Plasma Tests:** ⁣Green tubes are utilized for tests that require plasma ‍samples, such as certain drug level tests.

– **Specialized Tests:** Gray top tubes are utilized for glucose testing, ‍preserving the sample and avoiding glycolysis.

## Best Practices for⁣ Phlebotomy Collection

To make sure that blood samples are drawn and preserved ⁣correctly, following best​ practices‍ is vital. Here are several essential tips for phlebotomy professionals:

### 1. **Tube Order of Draw**

Always adhere to the correct order of draw to prevent contamination:

– Blood culture bottles
– Light blue (coagulation)
– Red top (serum)
– Gold or tiger top (serum separator)
– Green (heparin)
– Lavender ⁢(EDTA)
– Gray (fluoride)

### 2. **Labeling Samples**

– Ensure all tubes are correctly labeled immediately​ after‍ collection with ⁣patient information and date/time of collection.

### 3. **Avoiding Hemolysis**

– Use appropriate-sized needles and gentle handling of blood to minimize hemolysis, which can⁢ interfere with test results.

### 4. **Proper Storage**

– Store tubes in appropriate conditions as per guidelines (temp, light exposure) to maintain sample integrity.

### 5. **Training and Competence**

– Continuous training for phlebotomists helps ‍maintain ​high standards of practice and ‍ensures patient safety.

## Case⁢ Studies: Real-World Applications

### Case⁣ Study: Misdiagnosis Due ⁢to Incorrect Tube Use

In ‍a healthcare setting, a patient underwent a series of tests ⁤following complications from​ a surgical procedure. Unfortunately, a lavender top tube was used instead of a light blue⁤ tube for a coagulation test. The test results indicated ⁢a false ⁢diagnosis of a coagulation disorder, leading to unnecessary treatment. Upon review, ⁤the lab highlighted the importance of adhering to proper tube selection.
