Coeliac blood tests: talk before removing gluten
If coeliac disease is being investigated, changing your diet before the tests can change what they show. Tell the clinician whether you already avoid gluten before choosing a catalogue item. Coeliac disease, wheat allergy and a self-described food sensitivity are not interchangeable diagnoses.

Use the antibody names on the request
A common blood assessment includes tTG-IgA and information about total IgA; the clinician may choose other tests in particular circumstances. Ask what the proposed antibody investigation can establish and whether another assessment, such as a biopsy, may be needed. A general “gluten panel” label is not enough detail.

Explain what you currently eat
NIDDK advises against starting a gluten-free diet before diagnostic testing because it can affect results. If you already restrict gluten, ask for an individual plan rather than secretly restarting it or assuming a negative result settles the question. Do not provoke a suspected allergic reaction at home to prepare for testing.
Take the result back to the clinical question
Bring symptoms, family history, earlier investigations and the full report to review. A positive antibody result needs the appropriate next step; a negative result may need context if preparation or the clinical picture raises concerns. Do not use the catalogue to diagnose yourself or impose a restrictive diet on another family member.

Common questions
Can I diagnose coeliac disease from symptoms?
No. Symptoms overlap with other conditions and appropriate investigation is needed.
Should I start avoiding gluten before testing?
Discuss the plan with the clinician first.
Is a food-allergy panel the same investigation?
No. Confirm the specific question and markers.

H. pylori tests: active infection or past antibodies?
A catalogue may list several H. pylori tests, but they are not interchangeable answers to the same question. Ask whether your clinician is investigating a current infection or checking the outcome of treatment. That purpose helps determine the specimen and method, not the shortest turnaround or the largest package.

hCG blood tests: a number does not locate a pregnancy
A qualitative hCG blood test gives a positive-or-negative result; a quantitative test reports an amount. Neither result alone can confirm where a pregnancy is located. If pregnancy is possible and there is pain or bleeding, seek clinical advice rather than relying on a catalogue test to decide whether care is needed.

Practical questions
Urine ACR and blood creatinine answer different questions
An order for urine ACR is not fulfilled by measuring creatinine in blood alone. ACR compares albumin with creatinine in urine, while blood creatinine often contributes to an estimate of kidney filtration. Your clinician may need both types of information; do not substitute one because the names share “creatinine”.

Cortisol testing is not a simple stress score
Cortisol is involved in the body’s stress response, but a cortisol investigation is not a general score of how stressful your week was. Blood, saliva and urine tests can have different protocols. Select the exact clinician-requested investigation rather than whichever catalogue item has the shortest name.

Lipase and amylase: laboratory tests are not a pain triage
Severe or persistent abdominal pain should be assessed, not managed by choosing a pancreatic-enzyme test online. Lipase and amylase can contribute to a clinical investigation, but a number alone cannot determine the cause, severity or safe care setting for your symptoms.

Why an MMA test may follow a B12 result
An unclear B12 result does not automatically mean you need every vitamin test or an injection. A clinician may consider another investigation, such as methylmalonic acid (MMA), to clarify the question. Ask what the additional result would change before adding it to your laboratory order.
