I need help with my blood test results

Hi, I've been suffering from low testosterone since 20. I'm 33 now and I had a lot tested by the endocrinologist. My testosterone came back within normal limits but it was in the lower range. I don't know how to interpret my estrodial levels because there is no range. I'm trying to get a six pack and my body fat is 17%. I've been told that its going to be extremely difficult to gain mass with my testosterone levels.

Anyway, here are the results:

Serum testosterone levels - 9.3 nmol/l Range is between (8.4 - 28.7). My gp told me this was acceptable and I don't need any injections. I disagree with this because I had this level before and the previous doctor gave me the injection. I've contacted the endocrinologist's secretary and they don't know whether I should be back on the injections.

Sex hormone binding globulin - 25 nmol/l. Range is between (13.0 - 71.0). I don't understand what this is.

Serum Oestradiol level - 97 pmol/l. My previous reading was 87 pmol/l so I don't know why this has gone up. Once again no range has been given.

Serum prolactin level - 57 mu/l . Range is between (45.0 - 375.0). I don't understand what this is.

Serum sodium level - 136 mmol/l. Range is between (133.0 - 146.0) Don't understand what this is.

Serum potassium level - 4.0 mmol/l. Range is between 3.5 - 5.3. Don't understand what this is.

Serum urea level - 7.7 mmol/l. Range is between 2.5 - 7.8 Don't understand what this is.

Serum creatinine level - 79 umol/l. Range is between 74.0 - 110.0. Don't understand.

Liver function tests

Serum bilirubin level - 22umol/l . Range is between 1.0 - 21.0. I'm above range.

serum alkaline phosphatase level - 70 iu/l . Range is between 30.0 - 130.0.

serum total protein level - 71 g/l . Range is between 60.0 - 80.0.

serum albumin level - 44 g/l. Range is between 35.0 - 50.0)

Serum globulin level - 27 g/l. Range is between 18.0 - 36.0

Serum alanine aminotransferase level - 15 iu/l. Range is 0.0 - 40.0

Don't understand anything of the above.

Serum cortisol level - 299 nmol/l. Range is between 171.0 - 618.0

Serum LH level - 1.7 iu/l. Range is between 1.5 - 9.3

Serum follicle stimulating hormone level - 3.0 iu/l. Range between 1.4 - 18.1. I believe this is sometime to do with fertility.

Serum TSH Level - 0.04 mu/l. Range is between 0.35 - 5.5. Previous was 1.7 mu/l. I've been taking 250 mg levothyroxine for the last 6 months but now the gp has reduced the dosage to 200 mc.

serum free T4 level - 22.5pmol/l. Range is between 10.0 - 19.8) I'm above range.

serum triiodothyronine level - 5.0 pmol/l . Range is between 3.55 - 5.44.

prostate-specific antigen level - 0.6 ug/l. Range is between 0.0 - 3.0

Sorry, I'm 33 male, single, 167cm height, weight 9st 9 lbs, lean mass 8st, fat mass 1st 13.


I'm sorry I'm no expert on this kind of thing but I hope you find someone who can help you. I understand that if you are short of Zinc or Vitamin D your body might struggle to produce enough testosterone. Have you ever been tested? Do you have a family history of low testosterone and hypothyroidism?


Hi, I have no idea about the family history. My dad has diabetes. I was anorexic when I was 11/12 and was a vegan and this ruined my growth and development. I also believe this has caused all my medical problems. I had my zinc checked and it came back normal.


I'm hoping that someone on this site will help me with the blood test results because my doctor hasn't helped.
