High cortisol levels on 2 blood tests? Why?

High cortisol levels on 2 blood tests? Why?

How high?: It's important to know how high the tests were above the normal range (were they clinically significant?). Cortisol is produced by the adrenal glands which is under control by the pituitary. The problem could be either one. Your doctor who ordered the cortisol should be able to tell you the next step of workup. If the tests were indeed very high, you will need more testings before treatment. ...Read more

A blood test showed that i'm B12 deficient. Serum B12 level of 186 pg/ml, should I take vitamin B12 supplements?

A blood test showed that i'm B12 deficient. Serum B12 level of 186 pg/ml, should I take vitamin B12 supplements?

B12: this low will likely cause dementia, spinal cord degeneration and peripheral neuropathy. Keep your level above 550 for the rest of your life. Recovery takes about a year in a young person. I suggest you take liquid sublingual weekly for 3 months then bi weekly thereafter. Its important to check a level after you cut back to twice a month. Use 1 1/2 dropper and hold it under the tongue for 30 sec. ...Read more

Can u have hemochromatosis if your blood tests show high iron and tsat levels in 2 out of 4 tests over 3 years - t'ferrin & ferritin levels are normal?

Can u have hemochromatosis if your blood tests show high iron and tsat levels in 2 out of 4 tests over 3 years - t'ferrin & ferritin levels are normal?

Proper testing: The transferrin saturation needs to be done on fasting blood samples. A cut-off of 45% is best used. If the ts > 45% on fasting specimens, although the ferritin might be normal, can be seen with some iron overload disorders including hemochromatosis. A normal fasting ferritin and tsast. ...Read more

Could a TSH blood test detect low testosterone levels?

7 doctors agreed:
Could a TSH blood test detect low testosterone levels?

No: Tsh or thyroid stimulating hormone is only good for assessing thyroid function (either good, overactive or underactive). With that said, during that same blood draw, your blood could potentially be checked for testosterone to determine how much you have. This is best done in the morning. Remember that we really should treat the person (and symptoms), not just a number. Make sure benefit > risk. ...Read more

Low vitamin D 15, high calcium 10.6, then 10.2, PTH 67, endocrinologist told me to take vit D3 4,000 iu daily, but also added calcium, why?

Low vitamin D 15, high calcium 10.6, then 10.2, PTH 67, endocrinologist told me to take vit D3 4,000 iu daily, but also added calcium, why?

Consider hyperpara : These labs are borderline for hyperparathyroidism. The low vitamin D may be pushing the PTH up, but that doesn’t explain the borderline elevated calcium. You should repeat your vitamin D and be retested in a few months. This might bring clarity to your diagnosis. ...Read more

Vitamin D deficiency: The vitamin d deficiency has not been corrected. It is possible that there is poor absorption of vitamin d due to an intestinal problem. A gastroenterologist may be helpful. The elevated white blood cell count and red blood cell count should be evaluated by a hematologist. ...Read more

42yo male, blood test ->higher than normal estradiol levels & GI stool test ->high beta-glucaronidase - what's this mean? Take calcium D glucarate?

42yo male, blood test ->higher than normal estradiol levels & GI stool test ->high beta-glucaronidase - what's this mean? Take calcium D glucarate?

Get a consult: Most of this stuff about beta-glucuronidase in the stool comes from "independent medical thinkers" focused on gut flora and isn't mainstream. The scientific papers I've seen come from obscure institutions. And why are you having your estradiol checked? Reference ranges on labs are set so that a few percent of healthies fall outside on either end. I'd get a second, mainstream opinion. ...Read more

24-hr salivary cortisol tests showed dangerously low levels. One-off blood test showed abnormally high levels. Treatment with hc denied. Advice?

I'm puzzled: Please forgive my confusion. Have you had an acth stimulation test? With your history, you are right to be concerned about autoimmune addisonism. If you feel as if you have this, and/or are confused by your labs or have poor rapport with the physician who worked you up, it's time for another opinion. Stay proactive and good luck. ...Read more

Yes: The normal levels of fibrinogen range from about 150-400mg/dl. There are normal circumstances in which the level may be higher, e.g., pregnancy. Any lab value needs to be interpreted in the context of other health issues and this value may not be associated with a disease. Do consult the doctor who ordered the blood test. ...Read more

Dx vit d insufficiency, levels now gone up to reasonable level, but calcium gone high - can vit d3 supplements cause serum calcium results?

Dx vit d insufficiency, levels now gone up to reasonable level, but calcium gone high - can vit d3 supplements cause serum calcium results?

Vitamin D Metabolism: is tied closely with calcium levels through the parathyroid gland. PTH (parathyroid hormone) increases calcium by removing it from bone, increasing renal reabsorption and converting Vit D(D2 or D3) to Calcitriol. Calcitriol increases the amount of calcium that is absorbed from you gut. This shouldn't happen unless your parathyroid gland is overactive. Would ask your Dr. about this possibility. ...Read more

Will vitamin d deficiency cause low calicium level in blood?

Will vitamin d deficiency cause low calicium level in blood?

Yes: Severe Vitamin D deficiency(rarely seen in developed countries) can cause hypocalcemia. 25(OH)- D levels of 4.4 ng/ml (11 mol/L) or lower can cause hypocalcemia. Some of other causes of hypocalcemia include intestinal malabsorption, alcoholism, CKD, diuretics and hypoparathyroidism. Check ionized calcium level to confirm it is low. ...Read more
