Remember the order of draw:

You, Bring, Really, Good, Lollipops, Girl = Yellow, Blue, Red, Green, Lavender, Gray

Evacuated Collection Tubes

The "evacuated collection tubes" are glass or plastic and differs in length from 65mm - 127mm, the outside diameter of 10mm, 13mm, or 16mm. The mechanism of the rubber stopper on the tube has changed because of the increase of blood and body fluid precautions. The traditional rubber stopper popped as the top was removed to access the specimen. This created an aerosol that could be inhaled or ingested.

Expiration Date on Blood Tubes

Health care professionals have to acknowledge that blood tubes have an expiration date, to indicate when the tube should no longer be used. The tubes are good until the end of the month stamped on the tube. After the expiration date, the vacuum will possibly not fill the tube completely and the additives are not guaranteed to perform as it should. Using tubes past the expiration date affects the specimen and can give questionable results.

Upgrades of Blood Tubes

Tubes made from plastic are now used more commonly in health care settings. Different additives are added to the tubes to improve the quality of the specimen. These "additives" are not anticoagulants or preservatives but are used to improve specimen quality or to accelerate specimen processing. These tubes have a red stopper, red/black stopper, or gold stopper (Hemogard tube), depending on the manufacturer. The glass surface of a glass tube for serum testing will activate clot formation in the tube. Some glass serum tubes have a clot activator added to speed the clotting process. A plastic tube will not activate a clot; therefore a clot activator must be added to each tube during manufacture. This clot activator consists of silica particles on the sides of the tubes that initiate the clotting process.

Serum and plasma tubes can also be purchased with a thixotropic separator gel. This gel is and inert material that undergoes a temporary change in viscosity during centrifugation. It has a density that is intermediate to cells/clot and plasma/serum. When centrifuged, the gel moves up the side of the tube and engulfs the cells/clot, and an interface of gel forms that separates the cells/clot from the plasma/serum.

♥ Also, all blood tubes have a draw line on the tube, but the blue tube must be a full draw. ♥

Glucose Testing

Diabetes mellitus is a complicated disease that may cause more complications for the patient than just an increased blood glucose level. A person with diabetes mellitus often develop blindness (retinopathy), kidney damage (nephropathy), heart disease (cardiovascular disease), and circulatory problems that can result in tissue damage and amputation. Hyperglycemia is the signal that a person might have diabetes mellitus. The American Diabetes Association classifies diabetes as type 1 diabetes, type 2 diabetes, and prediabetes.

  • Prediabetes; Prediabetes is when a patient's blood glucose is higher than normal but not high enough to be classified as diabetic.
  • Type 1; The patient with type 1 diabetes is deficient in insulin production by the pancreas or in insulin function.
  • Type 2; 80 - 90% of diabetes patients have type 2 diabetes. Most patients of this type have a normal insulin concentration but lack relative insulin activity.

Fasting Glucose

The first step most physicians take in diagnosis diabetes is to draw a fasting plasma glucose for the patient. If the FPG level is greater than or equal to 126 milligrams per deciliter (mg/dl), the patient is diabetic.

Glucose Tolerance Test

The oral glucose tolerance test (GTT) detects borderline diabetes by measuring the patient's ability to dispose of a large oral intake of glucose.

A few of the factors can affect glucose tolerance and should be controlled before the test is performed. When a GTT is ordered, the patient should omit medications that are known to affect a glucose tolerance, have three days of unrestricted diet, and have unrestricted activity. The test should then be performed in the morning after an 8 - 16 hour fast. The patient should not be allowed coffee or cigarettes and should try to keep anxiety to a minimum.

Once you establish a business relationship with these Paramedical Exam Companies, you would need to set up a filing system. All patients and exam companies' files should be kept in a mini file cabinet. Also most of the Paramedical Exam Companies hire Independent Contractors "nationally," so it wouldn't matter what state you're in. You can work for them doing exams in your local area or farther. Keep the enthusiasm and know that your phlebotomy skill gets better with time.

      Hi Christine, every healthcare laboratory or clinic might not use gold or light green tubes for the same test that another healthcare place might use them for. As mentioned above in the article; some healthcare groups may use different color tubes than another healthcare group.
