Tests & Screens

Coronaviruses are a virus family that cause illnesses such as the common cold. In 2019, a new strain of the virus was identified, leading to a new disease that originated in China. This virus is known as severe acute respiratory syndrome coronavirus 2 or SARS-CoV-2 or COVID-19. Unfortunately, in March 2020, the World Health Organization declared the outbreak a pandemic.

There are several ways to avoid work-related injuries such as providing training, protecting mechanisms for managing risk examinations, and safety reviews. Another simple and preventive method is employment drug and alcohol testing. It is an effective way to create a safe work environment. This procedure can reduce the risk of hiring people who may pose a severe threat to themselves…

Chickenpox, or varicella, is a viral disease that is transmitted through particles transmitted by coughing, sneezing, or talking. When people get this infection, the immune system makes proteins called antibodies. Antibodies help the body to resist re-exposure to the virus in the future.Varicella Titer (or VZV titer or varicella antibody titer test) is another type of testing process that is used for checking the concentration of IgM and IgG antibodies in the blood.

Hep titer test is a type of immunity testing used to diagnose hepatitis A and B. Hepatitis is generally a viral disease that affects the liver. People who get the hepatitis A and B vaccine make a protein called an antibody in their body. Also, if a person gets infected, after a while, he makes antibodies in his body, which is called natural immunity.Titer testing basically looks for antibodies in the blood that are made due to receiving Hep A & B vaccines or after getting the infection.

The Respiratory Physical test is part of a physical examination that diagnoses the patient’s breathing system and lung function. This test is done by physicians to find out if the employee’s lung is performing properly. Once the physician has completed the physical evaluation, then diagnostic tests may be ordered to confirm the diagnosis.SNOHC can do pulmonary function tests, which determine the patient’s lung capacity.

Tuberculosis is an infectious and dangerous disease that affects the lungs. The cause of this infection is bacteria. The transmission agent of this disease is particles that are released by the patient while sneezing and coughing. In developed countries, the prevalence of tuberculosis due to the emergence of HIV has increased. Being infected with HIV causes the body to be unable to resist tuberculosis. Although the prevalence of tuberculosis in the United States is not so severe, tuberculosis is still a serious concern.

T Spot test is an in vitro diagnostic test that helps identify cells called effector T cells made by the immune system. These cells are made in response to the Mycobacterium tuberculosis antigen. Similar to the QuantiFERON titer test, the test is a single-visit blood test for TB screening.

Wearing a respirator is crucial for employees working in conditions where they could breathe in polluted air, vapors, or fibers. If you work in a hazardous area with harmful dust, fumes, gases, etc., the Occupational Safety and Health Administration (OSHA) requires you to wear respirators. You must conduct a medical examination and respirator fit test before wearing a respirator.

When sound waves stimulate the ear nerve, the message is transmitted to the brain, and hearing occurs. The intensity of sounds is measured based on decibels. If the sound waves are more than 85 decibels, it can lead to hearing loss after a few hours.The tone of the sound is also measured in cycles per second or hertz. In general, the normal range of human hearing is between 20 and 20,000 Hz.

Non DOT physical is a set of tests that determine work performance capability or assess the worker’s readiness to return to work. Many employers do this test for their employees to know if they are ready to perform their duties. These physical exams may have different names, such as work fitness assessment, fitness-for-duty examination, and pre-employment physicals.

Physical Exams

If an employee is injured at the workplace, no matter how severe, it’s considered as an occupational injury and it needs to be taken care of by the occupational health clinic in contract with the business. There are multiple reasons for occupational injuries.. They can happen due to trauma, wound, bruise, laceration, cut, chemical exposure, eye, heat, or musculoskeletal injuries.

Independent Medical Examination is a medical test to evaluate the patient’s physical, emotional, and mental state. This evaluation plays an essential role in worker’s compensation cases, personal injury litigation, and long-term disability claims. If there is an argument over a worker’s injuries, illness, or disabilities, he might need to undergo an IME. The physician must be competent enough to perform an IME and not be influenced by the patient or an interested party.

Some of the physical exams performed at SNOHC include post offer exams to new employees, annual exams for existing employees, department of transportation (DOT) or other specialized or required physical exams, executive physicals, return to work evaluations, asbestos physical, audio physical, FIT for Duty evaluations, Lift tests, and evaluations for medical conditions and those with chronic disease.

The purpose of this exam is to measure how well a patient’s hearing works. The audiometry test is to examine both the intensity and the tone of sounds, balance issues, and other items related to the function of the inner ear. A doctor who specializes in diagnosing and treating hearing loss, called an audiologist, administers the test. According to OSHA standards, all employees who are exposed at or above 85 decibels for eight working hours or an 8-hour time-weighted average (TWA) should consider this test.

The Respiratory Physical test is part of a physical examination that diagnoses the patient’s breathing system and lung function. This test is done by physicians to find out if the employee’s lung is performing properly. Once the physician has completed the physical evaluation, then diagnostic tests may be ordered to confirm the diagnosis.

The post offer employment evaluation is a set of examinations that show whether employees are physically fit to perform the job’s essential functions.
Post offer evaluations are not similar to what is done in pre-employment physical. You can do a post-offer physical for your worker if you have hired him/her.

Hazmat Physical exam is defined by OSHA (Occupational Safety and Health Administration) for workers who are exposed to hazardous substances. Also, if a worker is exposed to a hazardous substance that endangers his health, these tests will be performed to determine if he can return to work.

What does fit for duty mean? Fit for Duty (FFD) consists of an exam in which an employee’s physical, physiological, and psychological state is tested to evaluate how the employer can safely perform assigned tasks. Therefore, based on fit for duty definition, it is determined whether the employee can cope with the assigned tasks or not.

Asbestos, which is a mineral fiber, is found in soils and rocks. Asbestos fibers are flexible and soft yet resistant to heat, electricity, and corrosion. These qualities make the mineral useful. Due to its effectiveness, it has long been used in some industries and construction. But, long exposure to it can cause some serious health problems in you.

Needlestick injuries refer to wounds caused by accidental puncture of a needle into the skin. People who work with needle equipment such as hypodermic syringes, scalpels, and lancets are at risk for this type of injury.

Vaccinations

Laboratory services include a combination of tests performed on specimens of the body (for example, blood and urine). The purpose of these services is to diagnose, treat and prevent diseases. Some clinical laboratory services that help diagnose and treat diseases include:

Hepatitis A is a viral disease that causes inflammation of the liver. Your symptoms begin a few weeks after the virus enters your body. Although not all people may show symptoms, others may experience very severe symptoms. Fortunately, people can rarely die from hepatitis A.

Influenza (Flu) is a viral respiratory illness caused by influenza viruses. The infection attacks the respiratory system and is spread by droplets released while talking, sneezing, and coughing. Types of influenza virus are: A, B, C, and D. Influenza A and B cause seasonal flu in humans.

The MMR vaccine protects you against three contagious viral diseases called Measles, Mumps, and Rubella. This vaccine contains an active immunizing agent that causes your body to make a protein called an antibody against these viral diseases. In this way, the body will gain long-term immunity against these diseases.

Chickenpox or Varicella is a viral infection caused by a virus called varicella-zoster. This infection causes itchy rashes that appear as blisters on the skin. This disease can be spread by sneezing or coughing or direct contact without the vaccine. You could also get it by contact with fluid from chickenpox blisters.
The disease is highly contagious, and people who have not been infected or who have not been vaccinated are at risk.

Laboratory services include a combination of tests performed on specimens of the body (for example, blood and urine). The purpose of these services is to diagnose, treat and prevent diseases.


Can you still get COVID-19 after receiving the vaccine?

All You Need to Know on COVID-19 Vaccines


COVID-19 vaccines are generally made in a way that the body can be protected against the virus. Vaccines work by different mechanisms, but the ultimate goal is for the body to be able to produce enough B and T lymphocytes. B and T lymphocytes are a kind of white blood cells that are involved in making antibodies and attacking infected cells.

After vaccination, the body needs some time to produce enough B and T lymphocytes. So keep in mind that just after vaccination, there will be a possibility of getting infected. It’s because the immune system hasn’t had enough time to provide the necessary protection.
