Thick blood , high inflammation levels abnormal liver function in all 3 blood tests, test back pos for blood clot on lung after dye test, back neg?

Thick blood , high inflammation levels  abnormal liver function in all 3 blood tests, test  back pos for blood clot on lung after dye test, back neg?

This is serious: I trust the dye test was a pulmonary angiogram that demonstrated a pulmonary thromboembolus, and it has also been determined that you have hypercoagulable blood. This is a major problem that will require work with your primary care physician and probably long-term medical management -- more than healthtap can do. Hope you do not smoke. The "inflammation" & liver labs need to be addressed in time. ...Read more

My metanephrine free urine was 51, blood test was 63, normetanephrine free urine 181, blood test 150- total urine 232, blood test 213. Normal?

Sounds normal if....: the upper limits for blood metanephrine and normetanephrine are 0.50nm/l and 0.90nm/l. Urinary levels are, respectively: Total 24 hr. metanephrine =1.3mg for urine; and total plasma ME+NME is less than 205pg/ml. It sound as though you're within the normal ranges, but depending on the units of measure, which vary from lab to lab and med ctr to med ctr., you may not. Meet w/ your endocrinologist. ...Read more

Home pregnancy test was positive but blood hCG came back negative. Ob perform a blood test again. Hcg 750 progesterone 21. Why first hCG was negative?

Lab error: Presuming the first blood pregnancy test was close to the second, one of them had to be a lab error, probably the first one that was negative. If there is any question about the health of the pregnancy, your doctor can follow the bhcg level to see if it is rising appropriately and obtain an ultrasound when the level is high enough.For more info www.Askyourgynecologist.Org. ...Read more

Could a TSH blood test detect low testosterone levels?

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
