The TTP medical abbreviation most often means tender to palpation, a physical exam finding that an area hurts when the examiner presses on it. Less often, and in a very different setting, it means thrombotic thrombocytopenic purpura, a rare and serious blood clotting disorder.
The exam meaning fills emergency, primary care, physical therapy and surgical notes, usually with a body area next to it, such as TTP RLQ or TTP over the lumbar spine. The blood disorder appears in hematology notes, lab discussions and intensive care plans, with words such as platelets, schistocytes and plasma exchange. This page shows how to tell the two meanings of the TTP medical acronym apart and how each one reads in a chart.

Tender to palpation: the everyday TTP medical abbreviation
Palpation means examining by touch. When a clinician presses an area and the patient reports pain, the TTP medical abbreviation records the area as tender to palpation. It is an objective style finding written in the exam section, separate from the patient's own description of pain in the history.
Modifiers tell you more. Mild, moderate or severe TTP grades how much it hurts. The medical abbreviation positive TTP or (+) TTP simply means tenderness was present, and no TTP or NTTP means it was not. Location almost always follows, such as RUQ for the right upper part of the belly or the name of a muscle or joint.
The TTP medical abbreviation in the abdomen exam
| Exam line | Plain meaning |
|---|---|
| Abd soft, NTTP | The belly is soft and not tender anywhere |
| Mild TTP RLQ | Slightly sore when the lower right belly is pressed |
| TTP epigastric, no rebound | Tender just below the breastbone, with no pain on release of pressure |
| Diffuse TTP with guarding | Tender all over, with muscles tensing to protect the area |
Abdominal tenderness is one clue among many. Where it sits helps the clinician think about which organ might be involved, and other findings and tests complete the picture.
TTP medical abbreviation use in physical therapy
Physical therapists, chiropractors and sports medicine clinicians use TTP constantly when they examine muscles, tendons and joints. A note may record a tender point in a specific muscle, along with range of motion and strength.
Physical therapy note: "TTP R upper trapezius with palpable taut band, cervical rotation limited to 60 degrees on R." This means pressing a muscle along the top of the right shoulder caused pain and a tight band was felt there, and turning the neck to the right was limited.
Thrombotic thrombocytopenic purpura
In hematology, TTP names a rare disorder in which tiny clots form throughout small blood vessels. Each word of the name points to a feature. Thrombotic refers to clots. Thrombocytopenic means a low platelet count, because platelets are used up in those clots. Purpura means purple spots or bruises from bleeding under the skin.
Most adult cases are linked to a severe lack of an enzyme called ADAMTS13, often because the immune system makes antibodies against it. Labs typically show low platelets on a CBC and broken red blood cells called schistocytes on a blood smear. It is a medical emergency, usually treated in hospital with plasma exchange and medicines that calm the immune response. Pregnancy is one recognized trigger, which is why the TTP medical abbreviation sometimes comes up in obstetric care and pregnancy notes.
How to tell which TTP is meant
| Clue | Tender to palpation | Blood disorder |
|---|---|---|
| Section of the note | Physical exam | Assessment, plan, problem list |
| Words nearby | Body area, mild, no rebound, guarding | Platelets, ADAMTS13, smear, plasma exchange |
| Who writes it | Almost any clinician | Hematology, ICU, internal medicine |
| Related terms | Rebound, guarding, palpable mass | ITP, HUS, DIC |
If TTP sits right after a body part, it is the exam finding nearly every time. In cancer research papers, TTP can also mean time to progression, a study measure. The diagnosis abbreviations page lists many more condition labels.
Writing TTP clearly in a note
Always pair TTP with a location and, when possible, a grade, since a bare TTP tells the next reader very little. Record the absence of tenderness too, as NTTP or nontender, because a normal finding is useful history. If you write the blood disorder, many teams spell it out the first time to prevent mix ups with the exam meaning.
These are general notes on how the letters are used. Questions about pain found on your exam, or about platelet results, should go to the clinician caring for you.
Frequently asked questions
What does TTP mean in a physical exam?
It means tender to palpation: the area hurt when the examiner pressed on it. The note usually adds where, such as the right lower abdomen or a specific muscle.
What does mild TTP mean?
Mild TTP means slight tenderness when the area was pressed. It is one way clinicians grade how much an area hurts on exam.
What does positive TTP mean?
Positive TTP, often written (+) TTP, means tenderness was found. Negative or no TTP, sometimes written NTTP, means the area was not tender.
What is TTP in pregnancy?
In pregnancy, TTP usually refers to thrombotic thrombocytopenic purpura, a rare blood disorder that pregnancy can trigger. It causes low platelets and tiny clots and needs urgent specialist care.
Is TTP the same as ITP?
No. Both involve low platelets, but ITP is immune destruction of platelets without the widespread small clots and red cell damage seen in thrombotic thrombocytopenic purpura.
