The STAT medical abbreviation means immediately. It comes from the Latin word statim, meaning at once, and it marks an order that should be carried out before routine work, whether that is a blood test, a scan or a dose of medicine.
Most people know the word from television dramas, but in real hospitals STAT is a defined priority level. Labs, pharmacies and imaging departments each have target times for STAT requests, set by the facility. This page explains what a STAT order means in practice, how it compares with ASAP, now and routine, and why it is used with care.

What the STAT medical abbreviation means in a hospital
Every order in a hospital carries a priority. Most are routine and are done in the normal flow of work. A STAT order jumps ahead because the result or the treatment is needed for a decision right away. In a lab, a STAT sample is run before routine samples. In pharmacy, a STAT medicine is checked and sent to the unit first, and the nurse gives it as soon as it arrives.
STAT is written in capitals most of the time, though you will also see stat in lowercase. It is not a set of initials, so some guides call it a short form rather than a true abbreviation. Either way, it is read and said as one word.
Reading a STAT order line
A STAT tag can be attached to tests, imaging or medicines. This table breaks down a typical emergency department order set.
| Item | Plain meaning |
|---|---|
| CBC | Complete blood count |
| BMP | Basic metabolic panel, salts and kidney tests |
| Troponin | Blood test for heart muscle injury |
| ECG | Heart tracing, also written EKG |
| STAT | Do all of these right away |
Overheard at the nurses' station: "Can you call pharmacy, the STAT antibiotic still has not come up." The nurse means the medicine was ordered for immediate use and is now overdue against the hospital's target time.
STAT, ASAP, now and routine compared
Hospitals usually define several urgency levels, each with its own target. The exact minutes differ between facilities, so the table describes them in general terms.
| Priority | General meaning |
|---|---|
| STAT | Immediately, ahead of everything else |
| Now | Soon, usually within a short window set by policy |
| ASAP | As soon as possible, often less strict than STAT |
| Routine | In the normal schedule |
| PRN | Only when needed, not urgency at all |
A single STAT medicine dose is also sometimes called a one time dose given immediately, after which the regular schedule takes over. If an order reads 1 dose STAT then q6h, it means give one dose right away, then every six hours.
Why STAT is used carefully
If too many orders are marked STAT, the label loses its power and truly urgent work can be slowed down. For that reason, many hospitals review how STAT is used and remind staff to save it for situations where a delay could change care, such as a suspected stroke, a heart attack, sepsis or a sudden change in a patient's condition.
The Joint Commission does not ban STAT, and it is rarely misread. The main risk is overuse rather than confusion. Some hospitals also use separate alert names, such as a stroke code or a rapid response, which bring a whole team rather than speeding up one order.
STAT as a nursing and pharmacy abbreviation
Nursing students learn to treat a STAT order as the next thing they do, and to chart the exact time it was given. Pharmacy technicians learn that STAT orders are filled and delivered first, often with a different color label or a separate tube system run. Lab staff record the time a STAT sample was collected and resulted, because those times are tracked for quality.
Other urgency and timing terms appear in the prescription abbreviations hub.
Hospital priority rules vary, and this overview stays general. Your nurse or doctor can walk you through why a test or medicine was ordered and how soon it should happen.
