Question: Hi, can you tell me if saliva test are reliable or is blood work more reliable? I had both done and blood showed by testosterone to be 8 ng and saliva showed it to be 103! That's a huge difference! I'm a 44 year old female and had a total hysterectomy 5 months ago.

Brief Answer: In females blood work is more reliable Detailed Answer: Hi XXXXXXX Thanks for consulting us. There could be a number of reasons for this huge difference. Number one: both values may possibly be in different "units". That is, Testosterone levels can be measured in three different units e.g. ng/dl, pmol/L & nmol/L. So, both values may be in different units. So, cannot be compared unless a unit convertor is used. This can explain this huge apparent difference. Second possibility: could be "sampling at different days & times", as there is known variation with times of the day. Third possibility: is a "sampling error", which is very common with saliva testing. Forth possibility: is a known lack of sensitivity associated with saliva testing in females as they have low levels of the hormone. So, better to trust on your blood report, or you may repeat blood testing at a later date to further confirm your levels. Hope this solves your problem. Please write back if you have any question. Best regards.

Hello, My name is Coltyn and I am a 15 year old FtM (female to male) transgender. I have been taking testosterone enanthate intramuscularly and buserelin acetate nasal spray for 10 months, and have been taking 20 mg/day fluoxetine. I often get horrible stomach aches, had blood in my stool about a month and 1/2 to two months ago. Every day when I have a bowel movement, there is distinguishable food that hasn t been digested properly and is often very loose. I have consulted my paediatrician about the stomach aches and blood in my stool, but not about the undigested food. He says it isn t anything to worry about, but I m not sure if this information changes that. What is wrong with me?
