Active transport is a method of transport of ions or molecules along the cell membrane in the cell from lower to higher concentration region and which needs cellular energy.

There are three main types of Active Transport. They are:

1. The Sodium-Potassium pump,
2. Exocytosis, and

Given below are tubes color for which test test which one is used is given clearly. They are ::

Grey-Top Tube - Potassium Oxalate. This tube is used primarily for glucose tolerance testing.

Lavender-Top Tube - EDTA: EDTA is the anticoagulant used for most hematology procedures. Its primary use is for the CBC and individual components of the CBC. The larger (6ml) tube is used for blood bank procedures.

Red-Top Tube - This tube has no anticoagulant and is used for many chemistry tests, drug levels, and blood bank procedures.

Green-Top Tube - Sodium Heparin or Lithium Heparin

Navy Blue-Top Tube - There are two general types - one with K2 EDTA and one with no anti-coagulant. This tube is used primarily for trace metal analysis.

Serum Separator Tube (SST®) - This tube contains a clot activator and serum gel separator. It has no anticoagulant and is used for many chemistry tests. It cannot be used for certain drug levels or any blood bank procedures.

Yellow-Top Tube - ACD (Sol. A or Sol. B).

Blue-Top Tube - Sodium Citrate (NaCitrate): This tube is primarily used for coagulation studies (PT and PTT). Complete filling of this tube is essential to obtain accurate results.
