What Is An Analytical Testing Laboratory?

Having adequate testing resources is a key part of doing professional analysis. Most major universities have at least one laboratory that does qualitative (dyeing, identification) and quantitative (measuring concentration, spectroscopy) chemical tests. These laboratories are usually affiliated with a specific academic department or area such as chemistry, biology, or engineering.

Most individuals in academia have knowledge about these labs because they must take courses related to their field which often include practical applications for analyzing samples. More advanced students may also be assigned research projects that require using a quality lab for testing.

In addition to having access to a test kit, most labs will teach you how to perform the test correctly, give you detailed instructions, and walk you through it step by step. This way you can rely on them and learn from past mistakes!

Analytical testing is very important due to two reasons. The first is so we can tell if something is physically present in a sample. A common example of this is when people check sugar content in food to make sure they do not eat too much. If they find high levels of sugar, then they could potentially get sick due to a health condition called diabetes.

The second reason analytical testing is important is to determine what chemicals are present in a sample. For instance, someone might want to know whether there are natural toxins in meat before eating it or if there are contaminants in water coming into the home. Both of these cases would need appropriate testing done to ensure safety.

Reasons for using an analytical testing laboratory

An analytical testing lab is not a diagnostic clinic, nor does it conduct clinical tests. That would be practicing medicine without a license!

An analytical testing company performs non-clinical (or sometimes referred to as forensic) testing on samples sent in by you or someone else. These labs typically have specialties such as blood stain analysis, drug screening, DNA profiling, and infectious disease testing. Some even offer microchip scanning and investigation services.

Analytical testing laboratories are very popular these days due to their convenience. You no longer need to send your sample off to a geographically distant clinic that only offers primary care diagnoses. Your health really doesn’t matter too much when there’s a test at your fingertips that can tell you what’s wrong with you.

There are also legal reasons to use an analytical testing facility. For example, lawyers often require evidence of chemical exposure so they know how well people were doing before the incident occurred. They may also want proof of drugs being present so they can determine if someone was under the influence when the crime took place.

However, just because you’re legally allowed to do something doesn’t mean that you should. Only perform this test if you truly understand the implications and limitations.

Sample preparation for an analytical testing laboratory

Sample collection is one of the most important steps in any test that requires your blood, urine, saliva, or other fluid samples. If you do not collect the sample properly, then the results can be invalid.

For example, if you are trying to determine glucose levels using a blood test, then ensuring adequate heparinization (the lowering of blood clotting) is crucial. Heparin will interfere with the accuracy of the test unless enough is used.

Too much heparin may also cause bleeding! Therefore, professionals have standardized protocols for collecting various fluids such as blood, urine, or saliva. These protocols should be followed, even if you are doing this for educational purposes only.

In some cases, it is helpful to have someone else perform the collection for you. This removes the possibility of personal bias when performing the analysis.

Quality control in an analytical testing laboratory

What is an analytical testing laboratory?

A quality control (QC) department within most laboratories is responsible for ensuring that various tests are being conducted properly, using correct protocols, and that the results of those analyses are reliable and consistent.

This includes performing test calibrations to ensure that each test machine is working correctly, as well as verifying the accuracy of the reagents used in analysis.

Calibrating equipment can sometimes yield inaccurate or skewed results if the calibration is done improperly so it is important to know what tools should be used for this!

Test analysts who work in QC typically have specialties such as pH measurement, ion content determination, gas chromatography, etc. They make sure these areas are covered and that appropriate samples are analyzed according to protocol.

Some other duties include analyzing reference materials such as standard chemicals, human blood, bovine serum albumin, and others to determine their concentration of known analytes.

Equipment used in an analytical testing laboratory

An analytical testing lab has several pieces of important equipment, some more expensive than others. These include:

A spectrophotometer, which measures how light is absorbed by chemical samples

A gas chromatograph, or GC, which analyses volatile chemicals present in the sample

An ELISA (enzyme linked immunosorbent assay) reader, for determining levels of specific antibodies in the blood

A microplate reader, to read liquid samples such as blood

These are just a few examples — most labs have at least one of each! The reason that many laboratories have multiple versions of the same machine is because they specialise in different areas.

Some can test for both glucose and cholesterol, for example, using the same device.

Cost of using an analytical testing laboratory

The cost of using an external, professional diagnostic facility can be expensive depending on what tests you need performed. However, with the right research and knowledge, it is possible to find your own internal labs that offer similar quality services at a much more affordable price.

In this article we will talk about some ways to manage your disease without needing outside help. If you are conscious and aware of when your symptoms come and go, then why pay for someone else to check you for diseases when you do not have any symptoms? It is important to recognize if your symptoms belong to you or if they are beyond your body’s system because of a chronic illness. This way you can focus your energy on living rather than looking up diagnoses and finding out whether you qualify for medical insurance or not!

Some things cannot be determined from just examining yourself so it is best to see what external facilities have to offer. There are many different types of health checks that most laboratories offer, but none compare to having your blood tested in a lab setting by trained professionals. These professionals may also be able to run additional tests such as DNA profiling which can show if you are genetically predisposed to certain conditions like diabetes or cancer.

Sample treatment in an analytical testing laboratory

 

A good analytical test requires proper sample collection, appropriate storage of samples, and adequate preparation of specimens before analysis. These are called “sample treatments” or simply “treatments” for short.

Treatment of biological samples can be complicated to say the least. Different types of samples require different reagents and chemicals that must be stored properly and used correctly for accurate results.

There are several common treatments you will encounter as a clinical chemist. Many of these have funny names that may confuse both you and your patients! Here we will discuss some important things to remember about them when preparing samples for testing.

What is Iodine-Starch Test?

Iodine-starch tests look for glucose in urine by adding iodine to it and then reading how much starch reacts with the iodine. Glucose comes from all sources (carbohydrates) so this test does not distinguish between food, salicylates (examples: aspirin, ibuprofen), or other substances which would contain glucose.

This test can take up to two hours to complete depending on how fast each individual person metabolizes glucose. It should only be done at night when urination is more frequent to get better accuracy.

People who do not eat carbohydrates often do not need this test. Also, people who have been diagnosed with diabetes may already know if they are eating enough carbohydrates or not.

Analytical methods in an analytical testing laboratory

What is an analytical testing laboratory?

In addition to performing chemical tests for chemicals, most analytical laboratories also perform physical or spectroscopic analysis of materials. These additional analyses are referred to as analytic techniques.

Some common types of analytic technique include:

Optical microscopy – observing samples under a microscope using light and/or dye

– observing samples under a microscope using light and/or dye Electron scanning electron microscopy (ESEM) – examining surfaces by using electrons to determine composition

– examining surfaces by using electrons to determine composition X-ray fluorescence (XRF) – detecting material elements via bombardment with high energy x-rays

– detecting material elements via bombardment with high energy x-rays Energy dispersive X-ray Spectrometry (EDS) – identifying individual atoms within a sample using different levels of energy at which they break down

– identifying individual atoms within a sample using different levels of energy at which they break down Atomic absorption spectrometry (AAS) – determining the concentration of specific metals in a solution by vaporization and detection

– determining the concentration of specific metals in a solution by vaporization and detection Inductively coupled plasma mass spectrometry (ICPMS) – measuring trace amounts of heavy element isotopes in a solution

These advanced analytical testing tools use specialised equipment that is designed to work efficiently to ensure the best possible results.

Tips for using an analytical testing laboratory

A good diagnostic test facility will have clear instructions for use, sample collection tools, internal controls to ensure quality of tests, and clearly labeled reagents and supplies.

They may also offer online resources or apps that can help you run your tests. Some even have at home testing available!

By having this access, you don’t need to send off samples for analysis because they can give you results right here, anywhere you are. This is especially helpful if you are not in one place when symptoms occur or there is no way to get a specimen easily.

Running tests outside of the lab requires careful preparation and execution, making it difficult to determine whether the result was due to lack of expertise or poor health.
