How Long Do Lab Reports Take, and Why It Varies

How long a lab report takes depends on the test. Routine blood, urine and stool tests are usually quicker than culture, histopathology and molecular tests, and any time given is an estimate and not a promise. The lab confirms the reporting time when you book, because it depends on the test and on how the sample reaches the lab.

Why do some reports come sooner than others?

Each test has its own steps, and some cannot be hurried. A blood count is run on a machine and checked. A urine or stool test is looked at under the microscope. Those steps are short. Other tests need time that no lab can remove, because something has to grow, set or be read by a specialist.

What makes culture and sensitivity take longer?

A culture test grows the germ from the sample on a dish, which takes time, because germs multiply at their own speed. After that, the lab tests which antibiotics affect the germ, which takes more time. A Urine Culture & Sensitivity is therefore slower than a routine urine test, and there is no safe way to speed it up.

Why does a biopsy take longer?

A piece of tissue must be preserved, processed, cut into very thin slices, stained and then read by a pathologist who looks at the cells with care. A Histopathology / Biopsy depends on these steps. A good tissue report is worth the wait, because the vet may base serious decisions on it.

What about RT-PCR and ELISA?

Molecular tests such as the Canine Parvo RT-PCR are often run in batches, so that many samples are tested together and checked against controls. Some are done by an independent partner laboratory, which adds the time for the sample to travel and the result to return. Any time given for a referred test is an estimate. The lab tells you when it can if a test is delayed.

Routine tests such as the Complete Blood Count (CBC) are normally among the quickest, provided the sample is suitable and reaches the lab in good condition and in time. Even for these, the lab confirms the reporting time when you book, and the time depends on when the sample arrives, how many samples are waiting and whether any repeat is needed.

What can cause a delay?

• A sample that arrives late, damaged or in the wrong tube
• A result that is unexpected and must be checked again
• A machine or power fault, or a shortage of reagents
• A missing detail on the form that the lab must ask you about
• A holiday, bad weather or a transport problem
• A referred test that is held up at the partner laboratory

When there is a significant delay, the lab will tell you if it can. You can help the process by booking before you travel, sending a complete form, giving a phone number that you answer, and collecting the sample as your vet advised. If you have a deadline, such as a journey, a sale or a breeding date, say so when you book, so that the lab can tell you honestly whether the test fits it. A test that cannot be hurried is better planned early than chased late.

What should you do if your animal is unwell?

Never wait for a report before getting help. If an animal is collapsed, struggling to breathe, bleeding, having fits or seriously ill, call a veterinarian at once. A report is a tool for your vet, and a pending report must not delay urgent care. If a result is needed urgently for a decision, tell the lab when you book, and ask your vet to speak to the lab.

Reports reach you on WhatsApp, email and in My Reports on the website. A registered veterinarian reads them with your animal's signs and history. If you have not heard anything after the time you were given, call or WhatsApp the lab.
