Exploring Common Types of Venous Blood Collection Tubes in Urgent Care Clinics

Summary

• Vacutainer tubes
• Plasma tubes
• Serum tubes

When it comes to venous blood collection, there are various types of blood collection tubes used in urgent care clinics. These tubes serve different purposes and are essential for accurate diagnostic testing. In this article, we will discuss the common types of venous blood collection tubes used in urgent care clinics.

Vacutainer Tubes

Vacutainer tubes are one of the most commonly used types of blood collection tubes in urgent care clinics. These tubes come in various colors, with each color indicating the additives or anticoagulants present in the tube. Some of the common types of vacutainer tubes include:

1. Lavender Top Tubes: These tubes contain EDTA (ethylenediaminetetraacetic acid), which is used to prevent blood clotting by chelating calcium ions.
2. Green Top Tubes: These tubes contain sodium or lithium Heparin, which acts as an Anticoagulant by inhibiting thrombin.
3. Red Top Tubes: These tubes do not contain any Anticoagulant and are used for collecting serum samples.
4. Gray Top Tubes: These tubes contain Sodium Fluoride and Potassium Oxalate, which are used to preserve glucose levels in the blood sample.

Plasma Tubes

Plasma tubes are another common type of blood collection tubes used in urgent care clinics. These tubes are specifically designed to separate plasma from the blood cells through centrifugation. Some of the common types of plasma tubes include:

1. Blue Top Tubes: These tubes contain Sodium Citrate, which is used as an Anticoagulant by binding to calcium ions.
2. Yellow Top Tubes: These tubes contain acid-citrate-dextrose (ACD) or acid-citrate-phosphate-dextrose (ACPD), which are used to preserve platelet function in the blood sample.
3. Green Top Tubes: These tubes contain sodium Heparin, which is primarily used for plasma determinations in chemistry.

Serum Tubes

Serum tubes are used for collecting blood samples that require clotting to separate the serum from the blood cells. Some of the common types of serum tubes include:

1. Red Top Tubes: These tubes do not contain any Anticoagulant and are used for collecting serum samples.
2. Gold Top Tubes: These tubes contain a Clot Activator and gel separator to facilitate the separation of serum from the blood cells.

Understanding the different types of venous blood collection tubes used in urgent care clinics is essential for healthcare professionals to ensure the accuracy of diagnostic testing. By using the appropriate blood collection tubes, Healthcare Providers can obtain reliable and consistent results for patient care.
