Diagnostic Testing


Allergy Testing

Screening for allergies is necessary in order to identify the specific allergens that trigger reactions in sensitive individuals. By identifying the allergens, an allergy sufferer can avoid the offending substances as much as possible to reduce the frequency of episodic attacks, take medications to relieve symptoms, premedicate when exposure is likely, or undergo immunotherapy. Just as there are many types of allergic reactions, varying in symptoms and severity, there are many types of allergy tests.

After taking a medical history and performing a physical examination, the doctor decides whether an allergy test is necessary, and, if so, which one. In some cases, more than one test may be administered.

  • Blood Tests - Blood tests screen for allergies by detecting antibodies produced by the body's immune system. Blood tests are useful in finding a wide range of allergies, but are considered most helpful in diagnosing food allergies.
  • Skin Tests - IgE skin tests, also known as scratch tests, are very useful in diagnosing allergic triggers. During these tests, a tiny drop of a solution containing the potential allergen is placed on the skin and the skin is scratched or pricked to allow the allergen to invade the body. Skin tests are typically performed in the allergist's office to ensure proper results and to decrease the risk in case of a rare side effect or severe reaction.
  • Challenge Tests - are normally administered to diagnose an allergy to a specific food or medication. During challenge tests, a small amount of the potential allergen is either inhaled or taken orally. It is essential that challenge tests be supervised by trained allergist so appropriate measures can be taken in case of a severe reaction.

We offer this on-site in Yorba Linda at our Life Center and in South County at our Irvine location.


Cardiac Imaging

We offer on-site at our Yorba Linda office location.


Dexascan

A bone densitometry scan, also known as a bone density or DEXA scan, is a noninvasive procedure used to determine the extent of bone loss. The results can help assess a patient's risk of osteoporosis by measuring bone mineral density.

A dexascan is a simple procedure with no major risks and no need for anesthesia. Only a very small amount of radiation is used during this procedure, which will not affect the patient over a series of exams. After the risk of osteoporosis and related fractures is determined, patients can take certain precautions to reduce their risk of fracture and keep bones as strong and healthy as possible.

We offer on-site at our Yorba Linda office.

MRI

Magnetic resonance imaging (MRI) is a non-invasive, radiation-free scanning technology that is used to view detailed images of the tissues and organs within the body. During an MRI test, radio waves and magnetic fields are used to produce clear and detailed three-dimensional images of organs, as well as the hard and soft tissues throughout the body.

We offer at our Yorba Linda and Irvine office locaitons.


Nerve Conduction

Nerve conduction study (NCS), also known as a nerve conduction velocity (NCV) test, enables the diagnosis of possible nerve damage by measuring the speed with which an electrical impulse travels through a nerve. This test, often performed in conjunction with electromyography (EMG), allows the doctor to differentiate nervous system issues from musculoskeletal ones, and is invaluable in helping to establish the source of nerve damage, information that can be vital to effective treatment. Nerve conduction studies may be used to diagnose specific causes of nerve damages, including: substance abuse, nerve compression or various types of neuropathy.


Ultrasound

An ultrasound, also known as a sonogram, is a fast, painless imaging technique that produces images of the internal organs through the use of high-frequency sound waves. It is especially useful for examining the breasts, bladder, thyroid, abdominal organs and male and female reproductive organs, and for obtaining images of the fetus in the womb.

An ultrasound is a noninvasive, simple procedure that can produce images of soft tissues, which often don't show up well on X-rays. There is no ionizing radiation used during an ultrasound and there are no serious side effects of the procedure.

We offer on-site at both Yorba Linda and Irvine office locations.
