16 Diagnostic and Laboratory Examinations for Hypertension :

  1. Hemoglobin / hematocrit : assessing the relationship of cells to the volume of fluid (viscosity) and may indicate risk factors such as hypercoagulability, anemia.
  2. BUN / creatinine : provides information on perfusion / kidney function.
  3. Glucose : hyperglycemia (diabetes mellitus is the originator of hypertension) may be caused by increased levels of catecholamines (increase hypertension).
  4. Serum potassium : hypokalemia may indicate primary aldosterone (cause) or be a side effect diuretic therapy.
  5. Serum calcium : increased serum calcium levels can increase hypertension.
  6. Cholesterol and triglycerides in serum : increased levels may indicate the originator for / of the atheromatous plaque formation (cardiovascular effects)
  7. Examination of the thyroid : hyperthyroidism can lead to vasoconstriction and hypertension.
  8. Urine and serum aldosterone levels : to test the primary aldosteronism (cause).
  9. Urinalysis : blood, protein and glucose suggests renal dysfunction or the presence of diabetes.
  10. VMA urine (metabolites of catecholamines) : the increase may indicate the presence of pheochromocytoma (cause) ; Vanillylmandelic acid (VMA), a 24- hour, urine : it can be used for assessment of pheochromocytoma when intermittent hypertension.
  11. Gout : hyperuricemia has been the implication as a risk factor for hypertension.
  12. Steroids urine : the increase may indicate hyperadrenalism, pheochromocytoma or pituitary dysfunction, Cushing 's syndrome ; renin levels may also increase.
  13. IVP : can identify the causes of hypertension , such as renal parenchymal disease , renal and ureteral stones .
  14. Chest x-ray : may show calcification in the area of ​​valve obstruction ; deposit on and / ECG or aortic notch ; enlarged heart .
  15. CT scans : assessing cerebral tumor, CSV, encephalopathy, or pheochromocytoma.
  16. ECG : may show enlarged heart, a strain pattern, conduction disturbances. Note : Size, P wave elevation is one of the early signs of hypertensive heart disease.
