Where Are My Blood Test Results and How Long Does It Take?

Most routine blood test results reach your doctor within one to three working days, and urgent ones within hours. Specialised tests can take a week or several weeks. If you've ever asked "where are my blood test results and how long does it take?", the answer depends on the test, the laboratory and how your doctor shares results. So what holds up blood test results and how long does it take for each kind? This guide walks through it.

Key takeaways

• Routine results usually reach your doctor in one to three working days.
• Urgent and critical results are phoned to a doctor within hours.
• Specialised tests, such as cultures and genetic tests, can take days to weeks.
• Never wait for results if your symptoms get worse; get care straight away.

Symptoms That Shouldn't Wait for Your Results

Some symptoms need care straight away, whatever stage your tests are at. Call 000 or go to an emergency department for chest pain, severe breathlessness, fainting, confusion, heavy bleeding, vomiting blood or a high fever with a stiff neck or rash. If you have diabetes, very high or very low glucose readings with vomiting or drowsiness also can't wait. Worried about your blood test results and how long does it take to hear back while you feel worse? Don't wait. Symptoms vary from person to person, so if your symptoms are changing or new symptoms appear, call your doctor rather than waiting for a report.

What Causes Delays in Blood Test Results and How Long Does It Take?

Most delays come from the steps between your blood draw and your doctor reading the report. How long does it take to get blood test results? For a routine test, the pathology laboratory often has a result the same day, and the report usually reaches your doctor within one to three working days. A CBC blood test, the full blood count, is one of the quickest, and how long it takes is usually less than a day once the sample reaches the laboratory. And what about the rest of your blood test results and how long does it take for those? The quick, automated tests come first, and specialised tests follow over days or weeks.

Pathology results take longer when the sample has to travel from a regional collection centre, when it's collected late on a Friday, when the test is only run on certain days, or when an abnormal result is checked by a pathologist before it's released. How long do pathology results take to go to the doctor? Most pathology providers send them electronically as soon as they're final.

When should you worry about blood test results? Waiting a few days is normal and usually means nothing. Why do I need a blood test, and what do abnormal blood test results mean? A doctor orders tests to check for a cause of your symptoms or to monitor a condition, and an abnormal result means a number outside the usual range, which your doctor reads alongside your health and past pathology results.

How Urgent Requests and Critical Results Are Handled

An urgent request moves to the front of the queue, so the laboratory can have results within a few hours. If a result is dangerously abnormal, called a critical result, the laboratory phones the requesting doctor straight away, or an after hours doctor if the clinic is closed, rather than waiting for the report to be sent. So if you're asking how long does a blood test take when it's urgent, the answer is hours, not days. For people asking about blood test results and how long does it take when something is seriously wrong, that phone call is the safety net. How long does it take blood work to come back for a routine check? Usually a day or more.

How Your Results Reach You and Your Doctor

Your results go first to the doctor who requested the test, who reviews and interprets them. Blood workup results are sent electronically from the laboratory to your doctor, who then contacts you or discusses them at a follow up appointment. Some pathology providers also let you see results online, and some appear in your My Health Record, sometimes after a short delay so your doctor can look first. If you've wondered how long does a blood test take to show up for you, it's usually a little longer than it takes to reach your doctor. For a routine cholesterol test, how long does it take blood work to come back to you? Often two to five days. It's worth asking your doctor to interpret every result, because a single flagged number can look alarming without context.

Simple Ways to Avoid Delays With Results

A few simple steps cut down the wait. Have your blood taken early in the week and early in the day, so the sample reaches the laboratory before the weekend. Follow any fasting instructions for tests such as a cholesterol or glucose test, so the sample doesn't need repeating. Check your details on the request form, and book your follow up appointment when you have the test. If you've asked how long do blood test results take for you, a booked follow up removes most of the uncertainty. People who ask how long do blood tests take to come back are often waiting on one slow test, so ask your doctor which ones those are and how they'll interpret them.

When to Follow Up on Results That Haven't Arrived

Follow up with your doctor if you haven't heard about routine results within a week, or past the time they gave you. No news isn't always good news: results can be missed, sent to the wrong clinic or held up at the laboratory. When you call, ask which tests were done, whether all results are back, and what happens next. A comprehensive panel, such as a cholesterol, kidney and liver check together, may come back in parts. If you're unsure how long do blood test results take for your tests, or how long do blood tests take to come back for specialised ones, the collection centre can tell you whether the sample was received.

Why Specialised Tests Take Longer

Some tests take longer because the lab has to grow, process or send the sample on. A blood or urine culture grows bacteria in the lab for two to five days to find an infection and test which antibiotics work against it. Some hormone, antibody and vitamin tests are run in batches once or twice a week, or sent to a specialist lab interstate.

Genetic tests take the longest, often several weeks, because the lab reads and checks large amounts of information. A specialised laboratory may also repeat a test to confirm an unusual result before releasing it. Ask your doctor which of your tests are likely to be slow, so a delay doesn't cause worry.

Typical Turnaround Times for Routine Blood Tests

Turnaround times for most routine blood tests are short, measured from when the laboratory receives the sample to when the report reaches your doctor. If you're asking how long for blood test results of each kind, the table gives typical times; your own blood workup results may come sooner or later.

Frequently asked questions

How long does it take to get blood test results if something is wrong?

If something is seriously wrong, the laboratory phones your doctor within hours of finding a critical result. Less urgent abnormal results come with the routine report, usually within one to three working days, and your doctor contacts you to plan the next step.

How long does it take for blood test results to go to the doctor?

Most routine results go to the doctor within one to three working days of your blood being taken. They're sent electronically as soon as they're final, while specialised tests and cultures can take a week or more.

Yes. A doctor can tell you which of your tests are quick and which are slow, chase a result that hasn't arrived, and explain what each result means for you. A Medio GP can send an online blood test request where they think tests are needed, and talk you through the results by phone.

Do doctors call right away with bad test results in Australia?

Doctors in Australia are phoned straight away by the laboratory about critical results, and they contact you promptly when a result needs action. Results that are only mildly abnormal are usually discussed at your follow up, so book one and don't rely on no news being good news.

What would show up in a blood test?

A blood test shows only what your doctor asks the laboratory to measure. Common tests show anaemia, infection, kidney and liver function, blood sugar, cholesterol, thyroid levels and vitamins. Your doctor chooses each lab test you need to answer a question about your health. A laboratory test measures something in your blood, urine or another sample against a normal range, and the results will be available within a few working days.

What are red flags in a blood test?

Red flags in a blood test are results far outside the normal range, such as very low haemoglobin, a very high or very low white cell count, very high potassium or very high blood sugar. What will happen to my blood sample? It's tested, then stored for a short time in case a test needs repeating, and your doctor acts quickly on any red flag.
