Laboratory Testing in Chicago
Having regular laboratory testing is important to keep your health in check. Understanding your cholesterol levels, for example, helps you understand your risk for a heart att…ack. By having routine laboratory testing, you can prevent common health problems. With so many great laboratories throughout Chicago, there is bound to be a convenient location for you to have appropriate health tests done regularly. Here are some frequently asked questions regarding lab testing and where the best places in Chicago are to have your tests done.Quest Diagnostics and LabCorp are two major diagnostic laboratory chains with multiple locations. Both have locations in Chicago and its surrounding suburbs. Chicago's hospitals, such as Northwestern Memorial, Rush, Mercy, and Saint Joseph, all perform outpatient lab work for patients as well. Sometimes you can even get lab work done by a phlebotomist at your doctor's office. Be sure to check with both your doctor and insurance provider to find the best place to get your testing done.Diagnostic laboratories typically allow walk-ins and appointments. Some labs do not allow appointments to be scheduled in advance at all. If you plan to go to a Chicago hospital, such as Northwestern Memorial, you do not need an appointment. But calling ahead helps you avoid a busy period. Due to the frequency of fasting tests, these offices can become very crowded around 8 a.m. So if you are getting a fasting test done (one which requires you not to eat any solid food for a certain time before the test), it may be beneficial to make an appointment ahead of time if possible.You need a doctor's order to have lab tests done. If there are specific tests that you would like to have performed, you can request these from your healthcare provider, but they will order the tests. Be aware that hospitals in Chicago such as Rush Medical Center may only accept those with orders from the hospital's own doctors.Certain blood tests require fasting for the results to be accurate. This should be marked on your lab order. If you are unsure, contact your healthcare provider.You can always request patient pricing before having blood drawn. This is especially important if you do not have medical insurance. Testing can be expensive if you do not have insurance. For those with medical coverage, check with your insurance provider as many labs participate "in network" with certain insurances. This means that a larger percentage of the test costs are covered by the insurance company.From Chicago's major hospitals to your local doctor's office, there are places all over Chicago to have laboratory testing done. This leaves no excuse to postpone having your bloodwork checked. Laboratory testing can identify major health risks. By identifying these risks early, you can improve your health and prolong your life. If you ever feel that your doctor is not ordering necessary tests, be sure to request lab orders for additional testing at your next appointment.Drink plenty of water before having any blood drawn. Even if your tests require fasting for eight hours, you can still drink water both the night before and morning of testing. This helps increase blood volume, dilating your veins and making it easier for the phlebotomist to do their job. (MORE)

Supplies and Equipment in a Chemistry Laboratory
If you are taking a chemistry class, you have lab sessions that help you experience chemistry at work. You can conduct hands-on experiments under the guidance of a teacher and… other lab monitors. When you first enter the chemistry laboratory, you may be unsure how to use some of the supplies. However, if you take time to learn about each item in the lab, you should be better able to complete your experiments successfully.Beakers are glass containers of varying sizes. They usually have a lip around the top edge, and some include a spout to facilitate pouring. Beakers differ from flasks in that they have straight sides and a mouth as wide as its base. Flasks have a wide base and slanted sides that taper to a narrow neck.Bunsen burners are simple yet effective pieces of equipment. They are used in nearly every chemistry laboratory across the country. The gas flame produced by a Bunsen burner allows for controlled heating of substances and compounds within the lab. You can also sterilize items using a Bunsen burner or use the flame to ignite a substance.Pipettes come in a variety of different shapes and sizes. However, they usually look like long, narrow glass tubes. They are used to suction up liquid that has been pre-measured. Once the liquid is in the pipette, you can use the pipette to carefully release a controlled amount of the liquid into another substance or container.Funnels are cone-shaped devices with a small hole at the bottom. You can set a funnel over the top of one container and pour liquid into it. With this method, liquids can be moved from a larger container to a smaller one without spills.Goggles are essential pieces of safety gear for the chemistry laboratory. They protect your eyes from fumes, gases, stray drops of chemicals, and other hazards. Lab coats protect your clothing and skin from the chemicals you are using. Gloves keep your hands clean and protected as well. Be sure to wear your lab coat, goggles, and gloves whenever you are in the chemistry laboratory.If you need to temporarily store a small amount of a substance or liquid, a test tube is an excellent way to do it. Test tubes are short, round glass containers with rounded ends and stoppers that fit on the top, sealing the contents inside. Most test tubes are about the length of a human finger. The lip around the top of the test tube helps it fit snugly and securely into a test tube holder.Tongs and holders help you grip items in the chemistry laboratory. They are particularly helpful if a beaker, test tube, or crucible is too hot or if it is full of a volatile or hazardous substance. They enable you to manipulate the chemicals inside while maintaining a safe distance.As you work in your school's chemistry laboratory, you should become familiar with beakers, flasks, holders, funnels, and test tubes, as well as many other essential pieces of lab equipment. When you leave your lab session, make sure that you clean everything and return it to its proper place. Bunsen burners must be turned off, and your protective gear should be stowed according to lab standards. If you pay attention to detail and take care of the equipment in the lab, you are developing good laboratory habits that will carry you through your future laboratory experiences in college and beyond.Never conduct unauthorized experiments in a lab. If you have an idea for an experiment, tell your teacher or lab monitor about it. They can tell you whether the procedure would be safe for you to attempt. (MORE)

Stay Safe and Avoid These Common Laboratory Accidents
Although a hub for innovation and creativity, a lab can also be a very risky and dangerous place. This stems from the fact that numerous accidents occur in laboratories. These… accidents are caused by carelessness, disregard for lab rules, and a general apathy for laboratory procedures. Some of the common laboratory accidents are discussed in the subsequent paragraphs.Some of the most common laboratory accidents are cuts. They are usually caused by handling sharp instruments, broken glass, and other sharply edged pieces of laboratory equipment improperly. To avoid cuts, those in the lab need to handle items properly and walk with caution. Also make sure that all broken glass is disposed of in a special, labeled container.Though less common than cuts, laboratory accidents due to fires can have severe consequences. Small fires in the laboratory can be easily put out using water or a fire extinguisher. However, you should know where the fire alarm is and have an easily accessible phone by the door in order to contact emergency services. To avoid laboratory accidents due to fire, check the chemicals you use for fire hazard symbols and handle them with caution.A list of common lab accidents cannot be complete without the mention of burns. Most laboratory burns result from handling hot glass or metal ware with bare hands. Lab users should always use protective clothing like gloves when handling hot lab equipment or corrosive chemicals. Use crucible tongs and other gripping equipment when you can.Most lab chemicals are toxic and can have severe consequences when inhaled. A portion of these laboratory accidents may cause a person to choke, pass out, or even die. To avoid this laboratory accident, ensure proper ventilation, conduct highly toxic experiments in fume cupboards, and use gas masks when necessary.Although rare, explosions are one of the most severe laboratory accidents. The effects of explosions can lead to severe burns, loss of limbs, and even death. Take the following precautions to prevent explosions: * Avoid conducting experiments or heating chemicals in closed systems. * Use an explosion shield when carrying highly reactive chemicals.However small, all laboratory accidents can have serious repercussions. As a result, appropriate steps should be taken to make sure that a safe environment is created when conducting any experiment. Teachers, students, and lab technicians should abide by all lab rules and adhere to all safety procedures when carrying out experiments. By doing this, they will reduce the number of laboratory accidents.In 1675, Henning Brand, a German scientist, stored 50 buckets of urine in his cellar for month in the hopes that it would turn into gold. Instead, the urine turned into a waxy substance that immediately burst into flames. This element later came to be known as phosphorous. (MORE)
Staying Safe With Laboratory Safety Symbols
Have you ever wondered what those signs and symbols in chemistry lab actually mean? The skulls and shooting flames on some of the symbols can look intimidating. Intimidating i…s good. It catches your eye and warns you about potentially dangerous materials. Most of the laboratory safety symbols seem self-explanatory, but it's important to understand exactly what they are and what they do in order to help you avoid accidents and injury.In order to identify potential hazards quickly, a system of pictures was created to warn people of possible danger. Many of the symbols that you will see in a chemistry laboratory are based on the Globally Harmonized System or GHS. This is an internationally recognized system of nine symbols that indicate when a material is hazardous and what type of hazard it presents. There are also many other specialized symbols that are only be used in certain types of labs. These can require some sort of action, such as the use of safety equipment or alerts that indicate where you can dispose of waste materials.Safety symbols alert people to possible danger quicker than written explanations would. They are eye-catching, especially when paired with colors, such as red, to get people to stop and be cautious, or green, which alerts people to the presence of first aid. You don't have to know how to read or speak any certain language in order to understand these simple pictures, making them universally useful.The most common and recognizable safety symbols used for hazardous materials are the GHS symbols. They have three symbols indicating some sort of fire or explosive danger by using an explosion, or the image of flames. The symbol for compressed gasses looks like a simple sealed container. Chemicals that are corrosive use an image of a test tube pouring liquid onto skin or metal. There are two symbols that indicate a material is poisonous, the familiar skull and crossbones, or an exclamation point. For materials that can cause damage to the respiratory system, they use a symbol that looks like the upper torso of a person with gas inside the lungs. The last symbol identifies material that can be harmful to the environment by indicating a tree and a dead fish.While the hazardous material symbols are important, you should also keep your eyes open for other types of signs and symbols in your lab. Some of the most important ones are the first aid symbol, characterized by a white cross on a green background, and the symbol for the eyewash, which looks like a person washing out their eyes. Being able to identify these important safety features quickly is vital in an emergency situation. In addition to these symbols, there are also ones that indicate when you should use safety equipment in a specific area. These signs usually show a picture of what you need, such as gloves, goggles, aprons, or face shields.Whenever you are working in a lab, it is important that you pay attention to the signs and symbols in your workplace. They will alert you to possible danger, or to potential actions that need to be performed. Knowing what materials might be dangerous and what kind of danger they pose can help you avoid accidents and injury. So pay attention, learn what the laboratory safety symbols mean and how you need to react to them.If you are ever unfamiliar with a specific lab safety symbol, ask your teacher or lab manager. Ignorance can cause accidents. (MORE)
