Short stature — what specific test should we request?

Thank you for this article,¹ but I was miffed to see under investigations that there are none specific for growth hormone or other specialised tests. Getting bloods tests for children can be upsetting, and should we not get all the initial tests done at one time? So, may I ask what blood tests do you request when you first see a short child and why can’t these be done pre-referral so that the whole process can be streamlined? I accept that there may be a huge variation in interpretation of results, and many may need specific times of day or circumstances for a useful result. Coupled with the editorial about inequalities and the huge problem of GP scarcity, does it not make sense to get the correct tests done early?
