Lab Tests: What Are They?

Testing a sample of blood, urine, or another substance from a body is known as laboratory testing. Medical practitioners can determine a diagnosis, a course of treatment, and more with the help of these tests.

What Does a Laboratory Test Purpose?

Medical practitioners essentially employ lab tests to monitor, evaluate, diagnose, or do research on a patient’s condition. Doctors will request tests for a sample of blood, urine, or another body substance in order to obtain this information.

How Much Time Does a Laboratory Test Take to Complete?

The majority of lab tests can be completed in a few minutes. The collection of the specimens typically takes a few minutes as well. Furthermore, a great deal of in-hospital results can be obtained in three to six hours. On the other hand, the results could not be available for several days if the tests were conducted at other non-hospital facilities.

A Laboratory Test Can Be Administered by Whom?

Numerous healthcare professionals, such as pathologists, clinical laboratory technologists, technicians, and other medical staff, frequently conduct laboratory tests. Furthermore, some medical assistants might also do laboratory tests.

Medical assistants can do basic lab or screening tests at a doctor’s office in many states. The most popular tests include blood glucose levels, hemoglobin, red blood cell percentage, blood cell count, and urinalysis. Testing for strep throat or pregnancy can also be performed by a medical assistant.

Qualifications for Laboratory Examination

The standards for lab testing can change based on your job and area. Typically, those seeking to work as clinical laboratory technologists must hold a bachelor’s degree. However, technicians could just require a postsecondary certificate or an associate degree. It’s crucial to keep in mind that certain states demand licensing for technicians and technologists.

Candidates having healthcare experience may be given preference by some employers. Our Medical Assisting curriculum at Unitek College may provide you with a significant edge in job interviews for lab technician roles. Specimen collection, pharmacology, medicine administration, diagnostic imaging, and other subjects are covered in our courses.

Procedure for Laboratory Testing

You can begin learning more about the procedure for collecting specimens and conducting lab tests by following these steps. Of course, it takes time and effort to get good on lab exams, just like it does with any other talent. Nonetheless, don’t be discouraged if you don’t get things perfect the first time, and don’t be afraid to ask for assistance.

Laboratory Test Scheduling

Even though most exams don’t require much preparation, there are some rules that must be adhered to. Examining the relevant test description, which includes the specimen type, volume, process, collection supplies, patient preparation, and storage instructions, is one of them.

It’s also critical that you get the patient ready. Before an exam, they might need to fast or follow a certain diet in some cases. Certain tests may also necessitate some drug limitations.

Steps for Laboratory Testing

When conducting a lab test, you should adhere to the following common guidelines:

Get the patient ready ahead of time (fasting, drug limits, etc.).

Check the identify of the patient. A few instances of legitimate identifiers are the patient’s name, birthdate, and hospital ID.

Take a sample from the individual. Observe the regulations set forth by your facility and handle any biological material as potentially dangerous.

As instructed by your company or institution, process the specimen.

Keep the sample stored. Maintaining the specimen’s integrity and, by extension, the test results, depends on appropriate storage.


The patient can typically get back to their regular activities after the operation. For the most part, there is no recuperation period after a lab test. Always get advice from the attending physician if you are unsure.

Equipment Required for a Lab Test

Generally speaking, the following supplies are advised for lab tests:



sanitizer for hands

Container for specimens

Sample of body material

Urinalysis using urine dipsticks


centrifugal force


freezer or refrigerator

Difficulties or Possible Hazards Associated with Laboratory Testing

For patients, lab testing are frequently painless and safe. Blood draws may hurt, but it shouldn’t hurt too much or leave you permanently damaged.

Prenatal tests: what are they?

Why are prenatal tests necessary, and what are they?

Prenatal tests are diagnostic procedures performed on pregnant patients. They facilitate communication between your healthcare professional and yourself and your infant.

Several prenatal tests are administered to you at your prenatal care checks throughout your pregnancy. These tests ensure sure you and your baby are remaining healthy. Other tests are performed at certain intervals throughout your pregnancy. These prenatal exams look for a variety of health issues in your unborn child, such as:

birth abnormalities These are conditions related to health that exist from birth. They alter the way one or more bodily components are shaped or operate. Birth defects can lead to issues with the body’s functioning, development, or general health.

Genetic and chromosomal conditions. Chromosome and gene alterations are the root cause of many disorders. A gene is a component of every cell in your body that houses the information for how each cell develops and functions. The component of cells that houses genes is called a chromosome. Heart defects, sickle cell disease, and cystic fibrosis, also known as CF, are examples of genetic disorders. Down syndrome is a common chromosomal disorder. These problems occur on their own occasionally, and sometimes they are inherited from parents.

You might wish to speak with a genetic counselor if any family members have a history of certain medical issues. A genetic counselor is qualified to advise you on birth abnormalities and other hereditary medical disorders and how they may impact your health and the health of your unborn child.

What do diagnostic and screening tests entail?

testing for screening They do not specifically inform you whether your kid has a health problem; instead, they assess your baby’s likelihood of having one. A screening test carries no dangers for you or your unborn child.

Tests for diagnosis confirm whether your child has a medical issue. Your doctor could suggest a diagnostic test to validate the results of a screening test if it indicates that your child is very susceptible to a health issue. Some diagnostic tests may have some hazards for your baby, like miscarriage. A miscarriage occurs when a baby passes away before the 20-week mark of pregnancy.

The findings of screening tests can assist you in determining if a diagnostic test is warranted. If your infant has a medical ailment, you might or might not want to hear about it. You can find out more about your baby’s health and how to take care of him once he is born if you choose to get a diagnostic test. Another option is to arrange to give birth at a hospital where your child will get specialized medical attention.

Which prenatal exams are performed during the whole pregnancy?

These prenatal tests are available to you multiple times during your pregnancy:

Check your blood pressure. In order to rule out preeclampsia, your doctor takes your blood pressure. High blood pressure following the 20th week of pregnancy might result in preeclampsia. Serious complications during pregnancy might arise from preeclampsia.
test for urine Your doctor examines your urine to rule out illnesses like preeclampsia and infections like kidney or bladder infections. Urinary protein accumulation might indicate preeclampsia.
Blood tests. Your doctor tests your blood for a number of illnesses, including HIV, hepatitis B, and syphilis. Your blood test is also used to screen for anemia, determine your blood type, and determine your Rh factor. Lack of sufficient healthy red blood cells to distribute oxygen throughout the body is known as anemia. The majority of people’s red blood cells include a protein called Rh factor. It can trigger Rh illness in your baby if you don’t have it and they do. Rh illness can be avoided during pregnancy with treatment.

At every prenatal care visit, your provider will also take your weight to ensure that you are gaining the appropriate amount of weight.
