Elevated blood levels of ck-mb suggest damage to hear muscle and the test was used in the diagnosis of heart attacks. It has been superseded by troponin testing. ...Read more
BNP: Brain Natriuretic Peptide. In general terms BNP can be interpreted as follows. A normal BNP level makes the diagnosis of Heart Failure unlikely (rule out test) •A high BNP level makes the diagnosis of HF very likely (rule in or confirm test) •Intermediate values of BNP require careful interpretation, in light of patients age (consider age-adjusted cut-off values) and co-existing conditions. ...Read moreSee 1 more doctor answer
Mcv: The mcv- is mean cell volume, is the average volume of red cells, part of a complete blood count. Mcv is calculated from the hematocrit and red cell count (mcv= hct x 1000 / rbc (in millions per microliter). In anemia, MCV allows classification as a microcytic anemia (mcv below normal), normocytic anemia (mcv in normal range) or macrocytic anemia (mcv above normal. ...Read more

My blood work showed a level of 228 for alkaline phosphatase test. Will i need more test? What could it mean?
Yes: An elevated alkaline phosphatase will need to be evaluated with additional blood tests to determine why it is elevated. Most commonly this is due to some form of insult to the liver, usually alcohol. But even a cold can cause an elevated alkaline phosphatase. If your other liver enzymes are elevated, particularly, ggt, your doctor will likely order an ultrasound. ...Read moreSee 2 more doctor answers
Why would troponin and myoglobin show up at high levels in my blood work? What does CKMB or MB stand for in blood work?_
Talk to your doctor: Troponin and CKMB are both cardiac enzymes released into the bloodstream when there has been damage to heart muscle and are generally used as markers for heart attacks. Myoglobin comes from regular skeletal muscle when it is damaged and appears in your urine. If your total CK is in the 1000s then it might artificially raise the cardiac markers but can damage kidneys, either way see a doctor now! ...Read more

What does "Tsh with reflex(reflux?) to FT4" mean with blood work?Does that mean it's as complete thyroid check?
No: TSH (Thyroid Stimulating Hormone) is a marker for thyroid function. If it is abnormally high, the lab automatically (reflexively) does a Free T4 level. This is useful for diagnosing hypothyroidism, but it is not the same as a full thyroid panel. Hope this helps! ...Read moreSee 1 more doctor answer
My urine test shows creatinine is 1.3. Blood tests show urea 3.5 and persistent low egfr 55. What does it mean? What do I need to do? Feel really ill.
Find cause: Assuming your creatinine is blood level; mine runs 1.5 or so as i'm a muscle kind of guy but it's high for a lady. This old-fashioned pathologist doubts the value of in lab-generated egfr's in the absence of known kidney disease. Anything from serious disease to over-the-counter painkillers can raise creatinine / compromise the kidneys for at least a while. Follow up & consider other causes. ...Read moreSee 1 more doctor answer
What does it mean when I have an index value of 20.9 for a herpes i, ii, and IgG test? Lab results
Old infection: I do not know the reference value of the lab that did the test but i assume this is higher than normal and is interpreted as reactive. It means at one point in your life, you have been exposed to both varieties of hepres -i generally responsible for 'cold sores' and ii, generally responsible for genital lesions. However with diverse sexual practicess, they are becoming more interchangeable. ...Read more
