This is from the UK and about general surgery, not specifically OHS, but the testing looks about right, (but some of the names or initals of the tests may be different) ALSO because you are child bearing age, they will do a pregnancy test and I believe coagulations studies (pt ptt) are pretty routine for OHS to make sure your clotting time is normal, so they won't be surprised if you have bleeding issues and they can plan for it.

Full blood count (FBC)
This will demonstrate anaemia. This increases the risk of intra-operative hypoxia or increased cardiac workload. There is also an increased risk of myocardial infarction (MI) or cerebrovascular event (CVE) and delayed healing. It is also useful as a baseline measure of haemoglobin if the proposed operation is expected to cause substantial blood loss.
Urea and electrolytes (U&E)
Detects underlying renal deficiency and possibility of developing acute renal failure (ARF) after major surgery. It may also influence the choice of drugs given within the anaesthetic.
Liver function tests (LFT)
Does the patient have any underlying malnutrition? This may affect the patient's ability to heal.
Calcium
Is there a suggestion of underlying malignancy?
Clotting
Clotting and platelet function is relevant for the many patients who take aspirin or warfarin. Also patients with known clotting disorders.
Group and save (or hold)
Anticipating that there may be a requirement for blood, but not routinely for this procedure, the patient's blood type is identified and held, pending a possible (later) request for units of blood or blood products.
Cross-match
A requirement for transfusion needs to be anticipated to avoid high demand/unavailable resource. The surgeon makes a prediction (in units of blood) for the procedure. That amount, typed specifically for that patient, is held in blood bank for 24 hours. The decision about whether to cross match serum or to order group and save should be judged on the current haematological status of the patient as well as the estimated blood loss.
