Brief About the types of Phlebotomy Tubes

Yellow Top Tube

Yellow top tube contains sodium polyanethol sulfonate and is used for blood culture specimens or acid-citrate-dextrose (ACD solution A or ACD Solution B). The same tubes are used for HLA phenotyping and for conducting parental tests.

 

Phlebotomy Tubes Market

Light Blue Top Tube

Tubes with light blue stoppers/shields contain two additives: sodium citrate (3.2% or 3.8%) and CTAD (Citrate, theophylline, adenosine, dipyridamole). As an anticoagulant, citrate binds the calcium in blood that is needed for clotting. Since the additive still results in a whole blood sample — plasma and red blood cells, the coagulation tubes also contain buffered tri-sodium citrate solution. The amount of citrate concentration depends on a laboratory’s policies.

Red Top Tube

Tubes with red-colored stoppers are used for serology and immunohematology. Glass tubes don’t contain additives, but those made of plastic have clot activators. Plastic tubes need to be inverted to mix the blood with the coagulant. It usually takes 30 minutes for clotting to occur. Serology is done to check infectious mononucleosis, rheumatoid arthritis, syphilis, rubella titer, strep testing, pregnancy test, cold agglutinins, haptoglobin and C-reactive protein.

 

Green Top Tube

Phlebotomy tubes with green top contain sodium herapin, lithium herapin and ammonium herapin, all of which are coated in the inside of the tube. The herapin anticoagulant activates antithrombins that block the coagulation cascade and produce a plasma sample or whole blood. The same tubes are used for clinical chemistry and STAT chemistry tests.

 

Purple or Lavender Top

Tubes with purple or lavender-colored stoppers contain EDTA (ethylenediaminetetraacetic acid) additive that binds calcium ions, effectively blocking coagulation cascade. Clinical laboratories use these to test for whole blood.

 

Gray Top Tube

Gray-colored stoppers indicate that the tubes can contain potassium oxalate and sodium fluoride, sodium fluoride, and sodium fluoride/Na2 EDTA. These are often used for laboratory procedures where glycolytic inhibition of specimen is needed. Although red top tube can be used for a similar procedure, gray top tubes are preferred when there is a delay in having the glucose level tested. For adequate mixing of blood and additive, the tube must be inverted 4 to 5 times after specimen is collected.

The Art of Sabrage: Opening Champagne Bottles in Style

Image
Champagne   The opening of a champagne bottle is often accompanied by a sense of anticipation and celebration. While traditional methods involve carefully removing the cork, there exists a fascinating technique that takes this experience to a whole new level: sabrage. Sabrage is the art of opening a champagne bottle with a sabaler, creating a dramatic and memorable spectacle that adds an element of grandeur to any occasion. Derived from the French word "sabre," which means sword, sabrage requires skill, precision, and a touch of bravado. The process involves using a sharp-edged blade to strike the lip of the bottle, precisely at the seam where the glass meets the cork. The impact, combined with the internal pressure of the carbonated champagne, causes the glass to break cleanly, separating the neck of the bottle from the base in a spectacular display of flying cork and shards. According to Coherent Market Insights , the Champagne Market Size , Share, Outlook, and Opportun

ESD Bags are used to store sensitive electronic components that can be easily influenced by electrostatic discharge (ESD)

Image
An ESD bag is an antistatic bag used for storing electronic components. These components are susceptible to electrostatic discharge, a form of damage that can cause the entire system to shut down. An ESD bag keeps these electronic parts safe and secure. However, it can't protect all electronic parts from ESD. According to the " Coherent Market Insights " Global Industry Insights, Trends, Outlook, and Opportunity Analysis of ESD Bags Market . ESD Bags Market ESD bags are usually black. They contain vacuum-deposited aluminum. They meet two requirements: low charging and an electrostatic discharge shielding barrier. They also have a longer shelf life. Moisture protection is also a must. Prior to vacuum sealing, a moisture monitor card or desiccant pack is placed in the bag. Bondline offers both metallized and non-metallic barrier bags. The black ones are the most popular. A good ESD bag will protect electronic devices against ESD. Some of them are moisture barrier bags

Methods and Possible CAR T-cell therapy side effects

Image
CAR T-cell therapy, or chimeric antigen receptor treatment, could be a new variety of immunotherapy that uses specially engineered T cells to more precisely target cancer cells. The system is formed from cells and organs that employment together to stay the body safe from infection and cancer. T cells are one form of cell that hunts down and kills aberrant cells, including cancer cells. Because cancer cells can sometimes elude the system, it's necessary to retrain the system to recognise and fight cancer cells. CAR T-cell therapy could be a novel way of coaching the system to fight cancer. According to the "Coherent Market Insights" Global Industry Insights, Trends, Outlook, and Opportunity Analysis of CAR T Cell Therapy Market .   CAR-T Cell Therapy Market After a sample of a patient's T cells is taken from the blood, the cells are re-engineered to possess specific structures on their surface called chimeric antigen receptors (CARs). The receptors on these CAR
