Lab Testing Q & A

What's involved in lab testing?

Lab tests determine whether certain types of bacteria, viruses, or other abnormalities are present in bodily fluids and tissues. A lab test can provide Dr. Gastellum with a variety of information that allows her to make an accurate and complete diagnosis. Once she collects the sample, it goes to the laboratory for testing.

While many of the tests can be performed in the office, Dr. Gastellum may have the test carried out at a more advanced laboratory.

Dr. Gastellum uses a variety of lab tests including blood and saliva tests. Blood tests can show the number of red blood cells, white blood cells, and certain hormone levels. It also identifies the amount of both glucose and oxygen in the blood.

Saliva tests are also used to show hormone levels and are also able to indicate the presence of particular types of drugs and prescription medications.

Why are tests performed to identify hormone levels?

The entire human body runs on hormone interactions that occur throughout the body. The ovaries release estrogen and other female reproductive hormones. The adrenal glands release adrenaline that the stimulates other hormones that enhance the function of the body's other organs.

All your hormones work together to maintain the body's metabolism. When all of your hormone levels are within range, your metabolism boosts your energy levels and functions efficiently.

If you begin to experience symptoms of fatigue, nervousness, weight gain, and changes in how your body functions, Dr. Gastellum can use lab tests to identify which hormones aren't being produced in the correct amounts.

Can lab tests identify allergies and food sensitivities?

Lab tests can identify many different allergies and food sensitivities. When you consume food that you're allergic to, your body releases histamines and other substances that show up in both your blood and your saliva. Once you have an allergic reaction, Dr. Gastellum can perform a series of lab tests and uncover exactly what foods or substances you're allergic to.

By using the information gained in the lab tests, Dr. Gastellum can accomplish two things.

She can identify your potential allergen and provide you with information on how to avoid it in the future. She can also develop an effective treatment plan using both conventional methods as well as natural remedies that strengthen and support the upper respiratory system and decrease the severity of your reaction.
