What Causes Elevated Values Of Bhgc In The Absence Of Pregnancy?

Dear Doctors, I am 31 years old and are suffering from multiple sclerosis diagnosed four years ago and treated with the following therapies: from March 2011 to March 2014: interferon beta-1a (Rebif44 injection three times a week) from May 2014 to November 2014: Tysabri - monoclonal antibody (II line therapy) during these four years and goes, given the frequent relapses, too often have been forced to take on high-dose cortisone is that even during the last week of December 2014 I received infusions of 5 Solu-medrol 1 gram each. and finally 3 infusions of 500 mg each. just last week. I pretty much finished with the last infusion January 19, the day after I went to the hospital for the levies which have underlined the value Beta hcg 39.3. Since it is virtually impossible that I m pregnant (I m still a virgin), it has aroused no little concern. The same test was carried out by the Protocol for the beginning of the previous treatment, in May 2014 and everything was normal. I state that the initiation of therapy with interferon had a cycle quite irregular menstruation were abundant and lasting and this caused me a nagging anemia, in fact I went to the gynecologist, who after careful medical evaluation (including eco) prescribed me the Zoely who still assume though and from month to month barely macchio, the problem is solved. Sclerosis and anemia is not going quite agree. I redid the echo excess of zeal in 2013 and everything was always normal. In most assume Eutirox 75mcg every day for a thyroid nodule kept under control. To receive Tysabri, each month as I make the following screening tests and until now it was all in the standard: - Complete blood, transaminases, bilirubin, QPE, Creatinemia, BUN, electrolytes + Complete urine analysis. After all this talk, my question is high values of Bhgc in the absence of pregnancy, what are due? They must be of concern for something serious? All these medicines have affected the outcome? And the same cortisone, finished only the day before the levy, could affect the outcome? I apologize for the situation a little complicated, but I m starting to get scared. Thank you in advance for your attention lent.
