Practical questions
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.

Current infection and past exposure differ
A urea breath test and stool antigen testing can be used to look for evidence of active infection. Blood antibody tests may remain positive after infection has gone. An old positive antibody result cannot by itself show that treatment failed or choose another antibiotic course.

Preparation is part of choosing the method
Tell the prescriber about stomach medicines, antibiotics and other recent treatment before collection. Some can affect accuracy, and the timing plan must be specific to the requested test. Do not stop treatment yourself or follow a medicine-free interval copied from a forum. Ask how to rearrange collection if the agreed preparation cannot be followed.

Plan the review, not just the specimen
Keep earlier results and treatment dates for the clinician. Ask what a positive or negative result would mean in your situation and whether follow-up is required. Severe or worsening abdominal pain, vomiting blood or black stools needs urgent assessment rather than waiting for a routine catalogue test.

Common questions
Do all H. pylori tests show active infection?
No. Antibody results can reflect earlier exposure and need appropriate interpretation.
Does an old antibody result prove treatment failure?
No. Ask which test is appropriate for the post-treatment question.
Should I order another antibiotic course from the report?
No. Treatment decisions belong to the responsible clinician.

Iron profile, ferritin and CBC: what is actually included?
An 'iron check' may mean different measurements. Ask for the marker list so that a missing ferritin or CBC is not discovered after collection.

Practical questions
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.

Practical questions
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”.

Practical questions
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.
