Every Helvy guide is written by our health editors, then checked by a qualified clinician before it goes live and re-checked as the science moves. We name clinical roles, not individuals, until each reviewer has agreed to be credited publicly. This is wellness guidance to help you understand your own data, not a diagnosis.
QUICK ANSWER
In the NHS App, tap GP health record, read the notice, then tap Test results. You will see the marker, your number and the laboratory's reference range. You will not see an explanation. Tests done before October 2023 may be missing, and a clinician can hold a result back to discuss it with you first.
See which markers your results are missing →As of August 2026, the NHS App is where most people in England meet their own blood results for the first time. NHS England reported on 24 December 2025 that the app has passed 39 million registered users, and that November alone brought 20.8 million views of GP health records.
That is a lot of people reading numbers nobody has talked them through. This guide covers the three questions that follow: where the results are, why some are missing, and what the figures beside them actually mean.
1. Where are blood test results in the NHS App?
They sit inside your GP health record, one level down from the home screen.
- Log in and open GP health record.
- Read the notice about what you are about to see.
- Tap Test results.
- Pick a date to open that set of results.
Blood tests, urine tests and tissue biopsies all appear here, whether your GP ordered them or a hospital clinician did. Each line shows the test name, your value, the unit and the range the laboratory uses.
If the same test has been repeated, the app can draw a graph of it over time. NHS App help sets one condition on that: a graph is only available if the test has been done at least twice in the past three years and carries a reference range.
2. Why can I not see all of my results?
Four ordinary reasons, none of which means anything is wrong.
The test is older than the switch-on. NHS App help is direct about the cut-off: “If a test was carried out before October 2023, it may not appear automatically in your NHS App.” Your surgery can usually add older records on request, and that request takes time to approve.
The result is still with the laboratory. Most blood results reach the record within a few days. More involved tests can take weeks. Our guide on how long blood test results take has the usual timings.
A clinician has held it back on purpose. Guidance says a healthcare professional should delay releasing a result if they need to speak to you about it first. A gap of a few days is a normal part of that process.
Nobody ordered the marker. This is the big one, and the app gives no hint of it. A GP tests to answer a specific clinical question, so plenty of common markers were never requested. Vitamin D, ferritin and thyroid hormones are the ones people most often expect to find and do not.
3. What do the numbers and letters mean?
Every line has the same four parts. Read them in this order.
- The name or abbreviation, such as Hb, ALT or TSH.
- Your value, the only number that is yours.
- The unit, which differs between laboratories.
- The reference range, the local lab's normal band.
An H, L or asterisk simply flags a value outside that band. It is a prompt to look, not a verdict. Ranges are built from the spread of results in a local population, so the same value can sit inside the range at one hospital and just outside it at another. Our guide to UK reference ranges explains how those bands are set, and the abbreviation list decodes the short names.
If your results came from a standard blood count, the individual lines make more sense read together than one at a time. That is what our full blood count guide is for.
The wording your surgery adds is a separate language of its own. “Normal, no action”, “satisfactory”, “filed” and “review” each carry a different weight, and we translate all of them in the NHS results language guide.
4. What the app was never built to do
The NHS App is a window onto your record. It is not a consultation, and it does not pretend to be. The help pages say so plainly:
“You may see test results in your record that your healthcare professional has not yet discussed with you.”NHS App help, viewing test results
That single sentence explains most of the worry these pages cause. You can be holding a flagged number hours before anyone has read it with you. It is worth sitting with the fact that a flag on its own carries no meaning yet.
Two other gaps matter. The app compares your value against a laboratory band, not against how you feel, so an in-range result and real symptoms can sit side by side. And it can only show the markers somebody ordered, which is why people who feel unwell often find a short list and no answer. We wrote about that exact position in normal results, still feeling ill.
None of this is a fault in the app. It is the difference between a record and a reading.
5. What to do with what you found
If a result is flagged and nobody has called you, ring the surgery and ask what it means for you. Bring the date and the marker name. That is a fair question and a short conversation.
If you want to understand a number before you ring, our results checker explains what each common marker measures and what moves it.
If the list is shorter than your list of symptoms, the gap is the useful finding. A GP panel answers the question your GP asked. Vitamin D, B12, ferritin, thyroid hormones and cortisol are frequently absent, and the markers the NHS rarely runs sets out why.
Testing privately is one way to fill that gap without repeating what you already have. Take your NHS numbers, note the markers nobody measured, and test those.
READY TO TEST?
Fill the gaps your NHS results left
Helvy's home finger-prick panels measure the markers a GP form often leaves out, and every result arrives with plain-English context rather than a bare number. Results come back in around 5 working days from the lab receiving your sample, from UKAS-accredited UK laboratories.
Frequently asked questions
How long do blood test results take to show in the NHS App?
Most blood results appear within a few days of the sample reaching the laboratory. More complex tests, such as tissue samples, can take a few weeks. A clinician may also hold a result back deliberately if they want to discuss it with you first, so a short delay is normal rather than a sign of bad news.
Why can I not see my old blood test results in the NHS App?
NHS App help states that a test carried out before October 2023 may not appear automatically. Automatic access covers newer entries, so older results usually need your GP surgery to add them to the view. Ask the surgery for access to historic records, and allow a few weeks for the request to be approved.
What does the H or L beside my result mean?
It flags a value above or below the laboratory's reference range. The range is built from the spread of results in a local population, not from your own history, so a flag is a prompt to look rather than a finding. Values just outside a range are common and often mean nothing on their own. A qualified clinician reads the set together, alongside your symptoms.
Can I see hospital blood tests in the NHS App?
Often, yes. The test results section can include results from tests a hospital clinician ordered, as well as those your GP ordered, once they have been sent to your GP record. If a hospital test is missing, the result may not have reached the record yet, and the hospital team may contact you about it directly.
My results are all normal but I still feel unwell. What now?
Look at what was not tested. A GP panel answers one clinical question, so markers such as vitamin D, B12, ferritin, thyroid hormones and cortisol are often absent entirely. Speak to your GP about symptoms that persist, and consider testing the markers nobody has measured rather than repeating the ones you already have.
