What is Medical Testing?

Medical testing refers to the use of laboratory or in-office procedures to measure, detect, and monitor changes in the body. These tests help screen for diseases (including kidney disease or liver disease), diagnose medical conditions, evaluate organ function, and guide treatment plans. During a routine medical exam, testing may include blood work, a urine sample, or an EKG, among others. Each test provides vital insights into your health to help your healthcare professional determine the following steps in your care.

Different Types of Medical Testing

Blood Testing

Blood testing is a cornerstone of preventive medicine; it can measure red blood cells, white blood cells, glucose, cholesterol, proteins, and chemicals like bilirubin. Test results are evaluated against standard ranges, and any deviation may prompt further testing to determine the cause.

Urine Testing

A urinalysis assesses the concentration and presence of certain substances in the urine, including protein, glucose, leukocyte esterase, and bacteria. Samples may go through a dipstick test, microscopic exam, or visual exam so that our healthcare professionals look at every aspect of urinalysis results and check for signs of infection or kidney damage.

EKG (Electrocardiogram)

An EKG records the electrical signals in your heart; it is used to screen for irregular rhythms, blocked arteries, or past heart attacks. As part of both routine and executive exams, Dr. Cahill includes an EKG to monitor cardiovascular function and assist in early diagnosis.

Rapid Strep Tests

If you’re experiencing sore throat symptoms, a rapid strep test can quickly screen for Streptococcus bacteria. This helps ensure accurate diagnosis and timely administration of antibiotics when necessary, thereby avoiding unnecessary treatments.

Viral Swabs

Used to detect respiratory viruses, viral swabs are a fast and reliable method for identifying infections such as influenza or RSV. These are especially helpful when symptoms overlap with other illnesses and further testing is needed to determine the specific cause.

Things to Know About Medical Testing

Before your test, you may be asked to prepare by fasting, avoiding certain supplements or medications, or drinking more water to produce a concentrated urine sample. Always follow the specific instructions provided by your healthcare professional to ensure reliable results.

If you're providing a urine sample, proper collection using the clean catch method is essential, as an improper method to collect samples can affect results. After in lab testing, your test results will be reviewed by Dr. Cahill. Depending on what’s found, he may recommend lifestyle changes, more testing, or treatments such as antibiotics, dietary adjustments, or specialist referrals.
