Hi everyone.


I was just given the results of my son's amino acid urine test. "Essentially normal, but with elevated levels of taurine and hydroxyproline".


I am assumining the taurine excretion is because of the mag taurage, but I am confused by the hydroxyproline.


Can anyone shed some light on either of these? We are still in the middle of testing.


Also, does anyone know what the proper ration of copper and zinc are? I know that Great Plains runs a copper/zinc profile, but my pediatrician ordered them separately. So they are both in the normal range, but I wonder if the ration is at all significant.


One last question: should urinary OAT test be repeated every so often? He had one done a couple of years ago that was normal and I wonder if I should request a newer one. Also, he's pretty much at a low tic level right now. If he increases in the future, should tests be repeated then?

i honestly dont know anything about hydroxyproline Liane.


here is what Wiki has on it



It seems to be related to levels of collagen and gelatin? but I am a biochemistry dumbo so someone else will hopefully be able to give better input


the taurine would be elevated yes, because of the supplement, and as long as it is elevated within acceptable range to your doc, should be fine at being slightly higher IMO...unless it is not being properly metabolized, in which case the doc may recommend lowering taurine dose and maybe up the magnesium from other sources to compensate

Were the taurine levels slightly out of range or really high?


The hydroxyproline level is interesting. Here is some info on a couple of other threads that talk about connective tissue or excessive collagen.


Thread title "Cheri Glaucoma"

Cheri Glaucoma






Collagen is the main protein of connective tissue in animals and the most abundant protein in mammals, making up about 25% of the total protein content





Oh! And what is this about Cheri's son having a concave chest? My son has the concave chest too.





What is Pectus Excavatum?



A pectus excavatum may be caused by an excessive overgrowth of costal (rib) cartilage, low bone densities, poor nutrition and muscle imbalances. It is found more often in boys then girls. Pectus excavatum becomes more noticeable once the child enters periods of rapid growth such as during early adolescence. It is not uncommon for a child with a pectus excavatum to also have curvature of the spine (scoliosis), a hunched over posture (kyphosis) or Vitamin D deficiency (rickets).





Pectus excavatum is the medical term for an abnormality of the rib cage that results in a caved-in or sunken appearance of the chest. This condition, which is present at birth (congenital), is due to abnormal growth of the connective tissue joining the ribs to the breastbone (sternum). Usually, the abnormality is mild and needs no treatment.





There are numerous potential applications for tissue-engineered cartilage in head and neck reconstruction. These applications include laryngotracheal reconstruction, microtia repair, auricular reconstruction, and repair of septal defects. In order to characterize the differentiation of tissue-engineered constructs, a basic understanding of the collagen composition of different human cartilage subtypes is required.

Cartilage tissue can be divided into three general classes or types: hyaline, elastic, and fibrocartilage. In order to more precisely characterize these subtypes, immunohistochemistry with antibodies to elastin and to collagen types I, II, V, VI, X was performed.

just wanted to mention that my son's chest was concave at birth but filled out thereafter and is not concave now, nor has it been since infancy


he has real good posture and is 6 foot tall at 18yo, sees a chiro regularly re the adjustments needed from tics but has no spinal curvature or other skeletal malformations

As I have mentioned before, my guys are both tall too. From Chiro xrays, no curvature of spine or other skelatal problems either.


I think the last thing anyone wants to do is to try to fit everyone in any particular "box." From reading Yasko and other forums, the possibility of genetic combo's, regulating proteins/enzymes etc. is SO vast.


I do find the things discussed here to quite interesting though. No matter the stage of development or age is there a clue here?


Could a high level of hydroxyproline suggest collagen production or something "off" with connective tissue?
