This tube contains lithium heparin and gel separator used for the collection of heparinized plasma for routine chemistry tests. NOTE: After the tube has been filled with blood, immediately invert the tube 8-10 times to mix and ensure adequate anticoagulation of the specimen.Accordingly, how many times do you invert a tube?
Venipuncture Final
| Question | Answer |
|---|
| What is in a green tube and how many times do you invert it? | Heparin- 8 to 10 times |
| What is in a lavender tube and how many times do you invert it? | EDTA- 8 to 10 times |
| What is in a pink tube and how many times do you invert it? | EDTA- 8 to 10 times |
Beside above, what tests should be collected in royal blue top tube? Lavender stopper tubes contain EDTA and used for hematology studies. Royal Blue (EDTA) stopper tubes are mainly used for whole blood heavy metal testing (i.e., lead, manganese, chromium).
Also Know, what is the royal blue tube used for in phlebotomy?
This tube is used for the collection of whole blood for special studies. Royal blue-top tube: There are 2 types of tubes; one contains the anticoagulant EDTA and the other does not contain an anticoagulant. These tubes are used for preparing whole blood or serum for trace element studies.
Why do you need to invert the tubes?
All tubes (except red top tubes which contain no additives) must be gently inverted 5 to 8 times immediately after filling, to ensure proper mixing of blood and anticoagulant, or other additives.
| Tube cap color | Additive | Common laboratory tests |
|---|
| Green | Sodium or lithium heparin with or without gel | Stat and routine chemistry |
| Lavender or pink | Potassium EDTA | Hematology and blood bank |
| Gray | Sodium fluoride, and sodium or potassium oxalate | Glucose (especially when testing will be delayed), blood alcohol, lactic acid |
Use: EDTA whole blood or plasma. Send whole blood in a royal blue-top tube. Send plasma in a plastic transport tube labeled “Plasma, EDTA from royal blue.” Tan-top tube: Contains sodium EDTA for blood lead analysis.The draw order for specimen tubes is as follows:Blood culture.Blue tube for coagulation (Sodium Citrate)Red No Gel.Gold SST (Plain tube w/gel and clot activator additive)Green and Dark Green (Heparin, with and without gel)Lavender (EDTA)Pink - Blood Bank (EDTA)Gray (Oxalate/Fluoride)The tests each bottle is used for are the same: the purple one is for cell count, the yellow one is for electrolytes, albumin and LDH, the grey one is for glucose, and blood culture bottles can be used for fluid cultures.Centrifuge for the preprogrammed time or 10 minutes for red or gold top tubes, 10 minutes for green, and 15 minutes for BD Blue top tubes. If minimum g-force (1300g) cannot be achieved, spin for 20 minutes.| TSH |

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.Difference Between Plasma and Serum. Plasma is that part of the blood, which contains blood clotting agent called as fibrinogen, while serum is the fluid part of the blood and does not contain clotting agent. The another important role of blood is to provide nutrients, hormones, electrolytes to the cell.Plasma is obtained by separating the liquid portion of blood from the cells. Plasma is frozen quickly after donation (up to 24 hours) to preserve clotting factors, stored up to one year, and thawed just before use.3) The light blue-topped blood collection tube contains the additive sodium heparin.| CHOLESTEROL |

Order of draw is the tube sequence a certified phlebotomist needs to follow while collecting blood. Each tube is differentiated by the tube additive and color. A trained phlebotomist using the correct order of draw ensures they obtain a quality sample to be used for diagnostic purposes to provide accurate results.Sodium citrate is the preferred anticoagulant for coagulation measurements and prevents coagulation by forming a complex with calcium ions.ncG1vNJzZmiemaOxorrYmqWsr5Wne6S7zGifqK9doq6vxYytoKado2KxsHnYqKxmoZ6rsrPAjJpkq6eplrlursuunGaspZey
