Laboratory uses: Chemistry trace elements (such as Zinc, Copper, Lead and Mercury), toxicology, and nutritional chemistry testing The humble bandeau top – a firm favourite in every summer wardrobe, and one we’re here for on an eternal level. Every season, we update our collection with longline and cropped versions in varying prints, colours and amounts of detail. This time, it’s an Aztec extravaganza – the key player in your holiday ensemble for 2019. We love short shorts Red stoppers denote draws for serology and immunohematology. Plastic red-topped tubes typically have clot activators on their interior surfaces, while glass versions don’t. Tubes with SPS – For Blood and bodily fluid cultures (HLA, DNA, Paternity). The SPS aids in the recovery of microorganisms by slowing down/ stopping the actions of complement, phagocytes, and certain antibiotics.

When it’s hot out, our longline bandeau tops are best paired with shorts. Denim or jersey, the look is simple, sunny and summer-ready. You might even consider a longer chino style, which takes the look from beach to bar in a hot second. Now throw on your flip flops and go get that vitamin D! Fits for all However, there are certain situations in which they should not be used. They are inappropriate for any blood banking procedures. Furthermore, ammonium heparin tubes should not be used for ammonia determinations, lithium heparin for lithium measurements and so on. Red Top The tubes come pre-lined with various types of EDTA depending on the application. They keep white blood cells, platelets and other blood constituents stable (without coagulation) for up to 24 hours.

Royal blue-capped tubes have no additives and are usually made of special glass or plastic that will not contaminate the specimen. Phlebotomists use royal blue tubes to test: Light blue-topped tubes come with two main additives: CTAD (Citrate, theophylline, adenosine, dipyridamole) and sodium citrate at concentrations of 3.2 or 3.8 percent. PT (Prothrombin Time – evaluates the extrinsic system of the coagulation cascade & monitors coumadin therapy)

The blue bottle is used for haematology tests involving the clotting system, which require inactivated whole blood for analysis. Phlebotomists use pearl tubes for HHV-6, adenovirus and toxoplasma PCRs. Typically they contain a separating gel and EDTA. Pearl tubes typically draw 6 ml, with a minimum of 4 ml Gold Top Laboratory uses: Chemistry testing, especially glucose(sugar) and lactate, Glucose tolerance test (GTT)To activate red-topped tubes, phlebotomists must invert them several times to mix the solution. Clotting usually occurs within around 30 minutes. The red bottle is less common – it is used for biochemistry tests requiring serum which might be adversely affected by the separator gel used in the yellow bottle. Laboratory uses: Chemistry Testing (Plasma determinations in chemistry) : ammonia, carboxyhemoglobin & STAT electrolytes, chromosome screening, insulin, renin and aldosterone

APTT/ PTT (Activated Partial Thromboplastin Time – evaluates the intrinsic system of the coagulation cascade & monitors heparin therapy) The list below lists the most commonly used blood collection tubes, their additives and uses in laboratory: 1. Red This less commonly used bottle is for biochemistry tests which require heparinised plasma or whole blood for analysis. The calcium citrate is a powerful anticoagulant that binds to the calcium in the blood required for clotting. How much of the chemical the tubes contain is very much a function of the specifications of the manufacturer. Some are more liable to increase calcium citrate levels than others. Phlebotomists use yellow-topped tubes for DNA studies – such as paternity tests – and HIV cultures. The solution typically consists of a combination of citric acid, dextrose and trisodium citrate. TanWhat additive does: Sodium fluoride acts as an antiglycolytic agent to ensure that no further glucose breakdown occurs within the sample after it is taken. Potassium oxalate removes calcium and acts as an anticoagulant. Royal blue tubes are ideal for tests that do not require either coagulation or anticoagulation to generate reliable results. Pearl Top Most people think bandeau tops are best for the beach, but we beg to differ. These gems can be layered underneath sheer blouses and dresses – giving extra coverage when the autumn months come around. We especially love them with high-waisted jeans and over-the-knee boots. Aztec glamour

In many cases, there is no need to open purple tubes. Manufacturers design them for direct sampling. Sometimes, phlebotomists will use multiple different colors of vials for the same tests. Blue, purple and pink-topped tubes are sometimes interchangeable with yellow.
