I am trying to decipher my 20 year old daughter's labs as she is exhausted and has gained 60 pounds in a year and 1/2. My daughter got serious mono second semester of freshman year and had to return from college. Her Pediatrician said that the mono virus was affecting her thyroid at that time (January of 2011). The Thyroid portion of her labs said this:
FT4 (.93-1.60) 1.20
Thyroxine (T4) (4.5-12.0) 8.6
LCTSH (0.450-4.500) .877
Thyroid Perox AB (0-20) (77H)
ThyroGlobulin AB (0-40) 149(H)
At this point Her Pediatrician said they would just need to keep checking to see if the thyroid antibodies were permanently affected.
In the Summer when she rechecked them and was clear of Mono - the Results were:
Thyroid Perox AB: (0-20) 42 (H)
ThyroidGlobulin AB: (0-40) 55(H)
She was pleased that the antibodies were going down and the Thyroid seemed to still be functioning.
My daughter went back to College in the Fall and made it through the semester but was depressed, anxious, had gained a great deal of weight, exhausted and unable to focus on her work so we did not send her back in the Spring.
I took her to an Endocrinologist 02/12 one year from the Mono and Her results were:
Thyroid Perox AB: (0-20) 39 (H)
Thyroid Globulin AB
0-20) 68 (H)
FT4 Direct,S: (.82 - 1.77) .93
TSH: (.45 - 4.50) 1.2
He said she has Hashimotos but does not have a Thyroid Disorder and that we will just have to keep checking on it through the years.
I took her next to see a Naturopath to get his take on her low energy and other symptoms and showed him the labs and he said that 5.4 is pretty low given that her T4 was 8.6 a year ago when she first got Mono. He felt the Hashimotos was destroying her Thyroid pretty rapidly. He did say she would not be given medication until she crossed the borderline number. He also did some other blood work and the things that stood out were that her Ferritin Level was 11 which is very low and she was low on Vitamin D (who isn't?). He suggested a Gluten Free Diet and various nutritional supplements and Ultra Hematinic for the low Ferratin.
This is all a puzzle but we would love to get this sorted out and get her back to school. She is feeling a little better with the nutritional aids but nothing dramatic and she is constantly yawning. Thank you for any input! I worry so much!
PS - Why doesn't anybody test her T3??? And what is the Ferritin Connection? Does it cause the Hashimotos? Will the Thyroid antibodies go away as the pediatrician implied? Does the Hashimotos make my daughter tired or is it the low Ferritin?
