Blood Collection Tubes
Written by Collins Nwokolo

Doctors use a variety of methods to determine what illness a person is suffering from. One of the most common is collecting blood samples from this individual. A close examination of this basic human fluid can tell medical experts many important facts. It can reveal whether a patient is suffering from a chronic condition like cancer, diabetes, or AIDS/HIV. The test can also tell whether the various organs are functioning properly and the impact of medicines. This is one aspect which most of these professionals can’t ignore. Only after this diagnose can the physicians proceed with the proper treatment. It is a safe, risk-free and very common procedure.

 

How do pathologists collect blood from a patient’s body?

The process of collecting blood from an individual’s body differs from one hospital to another. Normally, senior doctors assign this important task to their juniors or nurses. In many instances, even laboratory assistants can assume this responsibility. The pathologist carrying out the procedure first examines a patient’s body. This helps him/her determine where a sample can be taken from. Generally, it is the portion of the person’s arms near the elbow. The specialist proceeds to tie tourniquet (a small plastic tube) on the upper region of sufferer’s arm. This results in the accumulation of blood in the vein.  This professional then draws out a sample using a syringe. He then cleans and sterilizes the area to prevent any bacterial infection.

The pathologist then transfers this sample from the syringe to suitable blood collection tubes. After doing this; he/she cover such containers with rubber caps of various colours. These could be red, gold, blue, lavender, green, black or yellow. He/she proceeds to place the tubes on a tray and sends it to the laboratory. Their proficient specialists start analyzing the sample to determine what microbes are present in it. They then write up their conclusions in a report. They eventually send this document to the doctor diagnosing the patient. On the basis of this information, he/she can determine what is wrong with this individual. The medical expert then proceeds with the necessary treatment.

People need to understand an important fact. Collection tubes are the most important piece of equipment on any hospital or medical centre. They come in various size and cap colours. These vessels ensure the proper storage of a patient’s blood sample. Only then it is possible to transport them from the centres of the collection to the laboratory for examination.

Doctors and hospitals administrators in-charge of procurement are always looking for top quality blood collection tubes. After all, the laboratory assistants require large supplies of such vessels for various reasons. They can browse the internet to achieve this objective. These professionals will come across many online pharmaceutical stores dealing in such products. They shouldn’t hesitate to go through product description and price quotes of sites they visit.

Moreover, these specialists should carefully read the customers’ reviews. This can give them an idea of the market reputation of the manufacturer. Only then should they make their final decision.

Choosing The Right Blood Collection

1. Serum Tubes

Most likely the primary thing to make sense of is whether you are after serum, or whether you’ll have to prevent the blood from coagulating. Try not to get serum mistook for plasma – while they’re both the fluid, without cell part of the blood which can be gotten by centrifugation, the key contrast is that serum is the result of blood which has been permitted to clump, while in a plasma test, the thick cells are basically spun to the base.

So serum is, in basic terms, what stays in the blood after it clusters: a sans cell fluid that is likewise drained of coagulation factors. It very well may be a decent, stable method for estimating the blood’s proteins, lipids, hormones, electrolytes, etc. A significant number of these markers can be put away for quite a long time in the cooler, or solidified down and estimated in bunches later.

Serum (clump activator) tubes (shading reliant on brand; BD is regularly gold yet in addition red, Greiner is red). These cylinders have silica particles, which enact thickening. Some likewise have a gel to isolate the serum. Those without the isolating gel are possibly progressively valuable in touchy demonstrative testing. In case you’re searching for a protein that isn’t engaged with coagulation, this is a decent spot to begin.

•  Thrombin-based cluster activator tubes (orange): In spite of the fact that the silica-covered cylinders cluster inside around 30 minutes, the orange cylinders clump inside 5. They’re primarily utilized clinically for tests that are required particularly rapidly. In any case, a portion of the serum parts are somewhat less steady in these cylinders.

2. Anticoagulant Tubes

This is the class to consider on the off chance that you need cells or plasma (without cell fluid which still contains coagulation factors).

• EDTA (Purple)

EDTA avoids thickening by chelating calcium, a basic part of coagulation. This is your essential hematology tube (by which I mean recognizing and tallying platelets, blood composing and so on). Plasma put away from EDTA blood can likewise be utilized to gauge most proteins, and hereditary material can without much of a stretch be put away from EDTA buffy coats (the interface between the red cells and the plasma after centrifugation, containing white cells and platelets). Note: these cylinders contain either K2EDTA or K3EDTA.

 

• Sodium Citrate (Light Blue)

For coagulation and platelet work tests. Like EDTA, citrate acts by expelling calcium from the blood. In contrast to EDTA, it’s reversible – so calcium can be added back to consider coagulation under controlled conditions. Citrated plasma is additionally used to quantify coagulation-significant components. It’s significant that a citrate cylinder ought not to be the primary sort of cylinder filled after venepuncture – an initial couple of mL of blood drawn will be somewhat initiated. In the event that you just need citrate for your venture, at that point you should gather a dispose of cylinder first. Likewise, note that diverse centralizations of citrate are accessible from various organizations.

• CTAD (Also Light Blue)

CTAD represents citrate, theophylline, adenosine and dipyridamole. These aren’t generally utilized; however, merit thinking about – they forestall ex vivo actuation of your platelets, making them helpful for some increasingly delicate platelet capacity and coagulation considers. Note that CTAD is light-touchy, so keep these folks in obscurity.

• Lithium/Sodium Heparin (Green)

Comparative being used to serum cluster activator tubes, however appropriate for tests in plasma instead of serum. Like the serum tubes, heparin cylinders can likewise accompany an isolating gel. Heparin acts by restraining thrombin arrangement. Note: if your endgame is PCR, you should realize that heparin is especially known to meddle with PCR responses. Be that as it may, whichever anticoagulant you pick, you may need to consider it in your response blend.

• Sodium Fluoride (Color Dependent on Brand; BD is Gray, Greiner is Black)

Sodium fluoride is an antiglycolytic specialist, so these cylinders are utilized for glucose and lactate testing. They likewise contain an anticoagulant (there are diverse sorts accessible).

• Corrosive Citrate Dextrose – ACD (Yellow)

These ones are not normal. However, they are utilized for blood and tissue composing and DNA investigation.

• Sodium Polyanethol Sulfonate – SPS (Also Yellow)

SPS balances out bacterial development. Valuable for microbiology.
For explicit purposes, there are more blood accumulation tubes out there, however ideally this has given you an idea about where to begin. Good fortunes, and welcome to the universe of – let’s face it – feeling only somewhat like a vampire.
