Order of draw is Yellow addictive is SPS blood culture invert 8-10 times. Light blue addictive is Sodium Citrate invert 3-4 times. Red addictive No clotting invert 5-8 times. Serum addictive Silica invert 5-8 times. Green addictive heparin invert 8-10 times. Lavender addictive EDTA invert 8-10 times. Last is Gray addictive Potassium invert 8-10 times
The color tube that contains sodium fluoride as an additive is typically gray. Sodium fluoride is added to inhibit glycolysis in blood samples for glucose testing.
The gray tube, also known as the lavender top tube, typically contains the anticoagulant additive EDTA (ethylenediaminetetraacetic acid) to prevent blood clotting. It is commonly used for whole blood hematological tests.
A gray tube is typically used for a glucose tolerance test. This tube contains sodium fluoride as an additive to preserve glucose levels in the blood sample.
Gray top tube (GTT) is typically used for glucose tolerance test.
The tube top used for a glucose draw is typically gray. This tube contains sodium fluoride as a preservative and potassium oxalate as an anticoagulant to prevent the breakdown of glucose in the sample.
Sterile, Light Blue, Red, Gold, Green, Lavender, or Gray. ie "Lavender last" rule is true unless you have a test requiring the gray tube which contains oxalate.
The color tube that contains sodium fluoride as an additive is typically gray. Sodium fluoride is added to inhibit glycolysis in blood samples for glucose testing.
The gray tube, also known as the lavender top tube, typically contains the anticoagulant additive EDTA (ethylenediaminetetraacetic acid) to prevent blood clotting. It is commonly used for whole blood hematological tests.
The additive in a gray tube often refers to a specific type of sealant or adhesive, commonly used in construction or automotive applications. For example, gray tubes may contain polyurethane or silicone-based sealants that provide waterproofing and flexibility. It's important to check the label or product specifications for the exact chemical composition and intended use.
A gray tube is typically used for a glucose tolerance test. This tube contains sodium fluoride as an additive to preserve glucose levels in the blood sample.
There is no order of draw. A comprehensive metabolic panel is just one tube, an SST or serum separator tube.
The additive in red-gray or red-black speckled collection tubes is typically a clot activator and gel separator. These additives help to separate the blood sample from the serum after centrifugation, allowing for easier testing of the serum without interference from clots or cells.

Gray tube
The first items you should collect are the serum or clot tubes. Then, follow this by other plasma tubes, then purple (EDTA), then blue (NA Citrate). The reason for this is that during the needle insertion, tissue substances (tissue thromboplastin, electorlytes, etc...) will enter the lumen of the needle and be aspirated into the tube initially. When performing certain tests (clotting studies, etc...) these trace substances may interfere with the results although that is really splitting hairs. So, best to clear the needle with clot tubes, then draw the others.Actually, the order of draw has changed....blood culture, blue (sodium citrate), serum or sst gel tubes (plain red, gold sst), heparin-sodium or lithium(light green, dark green), EDTA (purple), then gray(used for glucose screening).Actually it's:Here is the current order of draw according to CLSI standard H3-A6 is as follows.This should ALWAYS be followed to prevent erroneous results due to additive crossover:1.) Blood cultures (yellow) SPS (sterile)2.) Light blue (buffered sodium citrate tube)3.) Red (plain), or Tiger-Top mottled red (gel separator tube)4.) Green heparin and light green (sodium or lithium with or without separators)5.) Lavender (EDTA)6.) Pink, white, or royal blue (EDTA)7.) Gray (Na flouride/potassium oxalate)8.) Dark blue (FDHi I am taking phlebotomy and I agree with your answer but I would like to let you know what I have been taught-my teacher has been teaching/been a phlebotomist for 27 years.She taught us that the order of draw is:1.) YELLOW: Additive= SPS and Broth2.) LIGHT BLUE: Additive= 32% buffered,Na citrate3.) PLAIN RED: Additive= Nothing4.) SST(or 'tiger top' tube top tube): Additive= Clot activator5.) GREEN: Additive= Heparin,Na Lithium6.) LAVENDER: Additive= EDTA7.) GRAY: Additive= Oxalates8.) ROYAL BLUE: Additive= See labels,green heparin,plain red and lav.9.) YELLOW (tan): Additive= ADC and A/BI just Graduated from phlebotomy school, Jan 2011 and I was taught the Current Order of Draw is:Blood Cultures/SPS/Sterile(Plasma) Light Blue- Sodium Citrate *(Serum) Red- Plain "No Additive(Serum) Gold- SST= Serum Separator tube(Plasma) Light Green- PST- Lithium Heparin(Plasma) Dark Green= Sodium Heparin *(Plasma) Lavender/Pink- EDTA K2-EDTA *(Plasma) Gray- Sodium Floride and Potassium Oxalate*ALL OTHERS*= Anticoagulant Tubes Rim Plasma when centrifuged
