Endocrine System Disease Diagnosis
1 AnswerThe gastrinoma diagnosis should be suspected on the basis of the clinical presentation and established in almost all patients by demonstrating elevated basal gastric acid secretion (BAO) and fasting elevations of the protein gastrin, which is produced by the gastrinoma. It is this protein gastrin, which leads to the increased acid secretion causing the ulcer formation.

Doctors are typically able to diagnose endocrine system diseases by measuring your blood levels of endocrine hormones. Your doctor might need you to fast, take medication, or eat particular foods for a brief period prior to your blood test. Often, this is done to help stimulate your endocrine system to produce more of a particular hormone or hormones, in order to make it easier for your doctor to evaluate endocrine function.
1 AnswerThe CRH stimulation test will see if the body can increase the amount of cortisol and ACTH made by the body in response to corticotropin releasing hormone (CRH). Patients with Cushing's disease (pituitary adenoma) should be able to increase the levels of cortisol and ACTH while patients with an ectopic tumor usually cannot.
1 AnswerTo diagnose a thyroid nodule, a complete medical history and physical examination should be done by your physician. Pertinent signs and symptoms of the thyroid nodule should be discussed. The patient's neck should be inspected and then examined while sitting up at rest and again while swallowing. The firmness of the nodule and whether it moves easily should be noted.
To prepare for your appointment to diagnose an endocrine system disease you should do several things. You want to list your past history, family history, current history, and a list of questions that you want to ask the practitioner.
Past History should include the following:
- All previous and current illnesses and how you manage them
- Past operations or procedures
- Medications taken on a daily basis (include over the counter and supplements)
- Significant diagnostic and lab tests done in the past
- Any treatments or practices you are engaging
- Cultural Beliefs and Practices
- Social (alcohol, smoking, drug use)
- Past medical history of parents, grandparents, and siblings
- Manifestations and Symptoms
- Onset of symptoms
- Duration of symptoms
- Why you believe you have this disorder
- Previous doctor visits for this disorder
- Past or current treatment of this disorder (medications, therapy, etc)
- Results of any diagnostic tests (ideally bring reports with you to the visit)
Questions you may want to ask:
- What does it mean if I do have this disorder?
- What type of diagnostic tests will I have to undergo?
- How do I prepare for them?
- What type of medications might I need?
- What type of activity may I do or not do?
- What type of diet should I follow?
- What type of physical activity may I do?
- What are the potential complications?
- Is there a cure for this?
- What are the risks/benefits of treatment versus no treatment?
You may think of additional things to add but this should help. It always helps to bring a list and some blank paper and a pen so you can write down what the healthcare practitioner has told you about your disorder. It is also a good idea to bring a relative or friend for support.
1 AnswerIt is important to note that certain high blood pressure medications may interfere with the diagnostic tests for primary hyperaldosteronism and thus, after consultation with a physician, should be discontinued 4 to 6 weeks prior to testing. The best screening tests to determine if a patient has primary hyperaldosteronism are simple blood tests that measure the levels of potassium, aldosterone, and renin in the blood.
1 AnswerIn the 24-hour urinary excretion of aldosterone test, a patient eats a high-salt diet for 5 days before measuring the amount of aldosterone in the urine over a 24-hour period. In patients with primary hyperaldosteronism, aldosterone will not be suppressed by the salt load, and the level of aldosterone in the urine will be high.
1 AnswerA diagnosis of a glucagonoma is established with a significant elevation of glucagon levels in the blood. Other common laboratory abnormalities include elevated blood sugar and chromogranin A values, and anemia (decreased red blood cells). Symptoms of glucagonomas are often vague and may be evident for years before a diagnosis is secured. Consequently, the tumors may be relatively large (an average diameter of 4-6cm) when they are discovered.
1 AnswerIn the saline suppression test, the patient is given a salt solution through an IV, after which the levels of aldosterone and renin in the blood are measured. In patients with primary hyperaldosteronism, the level of aldosterone in the blood is still high and the level of renin is low even after this salt loading.
1 AnswerIn most patients with primary hyperparathyroidism (80%), only one of the four parathyroid glands is diseased. Localizing tests are radiology tests designed to help identify which parathyroid gland(s) are hyperactive. One such localizing test is a sestamibi scan which involves injecting a small amount of special radioactive material into a vein and taking an X-ray image of the chest, neck, and head. The advantages of a sestamibi scans are their widespread availability and their ability to evaluate for diseased glands outside of the neck.
