@JonMarkPerry If you take a look at this meta discussion you'll see that the focus here has changed and some things like the help section still need to be updated. This question is a bit obscure and could use some editing, but it's not off topic. – Carey Gregory♦ Nov 6 at 5:13

1That said, to the OP, could you please spell out your question a bit more in plain language? You're talking to a wide audience. – Carey Gregory♦ Nov 6 at 5:40

1@JonMarkPerry But its a question you would expect a medical student / a clinician to know, and this is the site for them. It’s not a site so that you can ask your GP, but a site where medical professionals share knowledge. Yes, that means we overlap with human biology, naturally – Narusan Nov 6 at 14:01
These skeleton diagrams are used as short hand to avoid having to write units and test names for lab values - you can just look at a diagram of numbers and know what they apply to. Sodium is always in the same place, as is K, Cl, etc.
The skeletons are as follows:
Na K Cl HCO3 BUN Cr Glu = Chemistry 7
if you add AST ALT Alk Phos TBili Prot Ca = Chemistry 14 (which are usually in vertical form).
- Your diagram has just the LFTs, which can be represented as in your diagram, or in others (it varies).
PT PTT INR = coagulation panel
pH PaCO2 PaO2 HCO3 SaO2 BE = ABG (Arterial Blood Gas)
WBC Hgb Hct Plt = key components of CBC (Complete Blood Count) without diff.
I found this example of writing the CBC diff, but have never actually seen it written out like that.
Per request, this is a Khan academy video on lab values. I couldn't find any formal resources on fishbone diagrams, they're kind of passed on in medical education...

1Might be useful to mention that you'll see a few different shorthand diagrams for LFTs, but I've never seen a different way to diagram a CBC or chem 7 – De Novo Nov 7 at 1:08

Are there any reputable references you can provide for background reading to what you have provided here? – Chris Rogers Nov 7 at 8:41

That's tough because most of this is just passed down, but I found a video from Khan academy – DoctorWhom Nov 9 at 14:40
