Science Term: Stool Sample

1.  Di dalam istilah sains, 'Stool' bukan saja bermaksud Bangku tetapi adalah hasil proses perkumuhan di dalam badan benda hidup seperti manusia dan haiwan. Ia lebih dikenali juga dengan nama 'Najis' atau 'Tinja'. Selain 'Stool' nama lain adalah 'Feces'.

2. Contoh yang di dapati di dalam Bahasa Inggeris, di dalam bidang perubatan:

A stool analysis is a series of tests done on a stool (feces) sample to help diagnose certain conditions affecting the digestive tract. These conditions can include infection (such as from parasites, viruses, or bacteria), poor nutrient absorption, or cancer.

For a stool analysis, a stool sample is collected in a clean container and then sent to the laboratory. Laboratory analysis includes microscopic examination, chemical tests, and microbiologic tests. The stool will be checked for color, consistency, amount, shape, odor, and the presence of mucus. The stool may be examined for hidden (occult) blood, fat, meat fibers, bile, white blood cells, and sugars called reducing substances. The pH of the stool also may be measured. A stool culture is done to find out if bacteria may be causing an infection.

Why It Is Done

Stool analysis is done to:

Help identify diseases of the digestive tract, liver, and pancreas. Certain enzymes (such as trypsin or elastase) may be evaluated in the stool to help determine how well the pancreas is functioning.

Help find the cause of symptoms affecting the digestive tract, including prolonged diarrhea, bloody diarrhea, an increased amount of gas, nausea, vomiting, loss of appetite, bloating, abdominal pain and cramping, and fever.

Screen for colon cancer by checking for hidden (occult) blood.

Look for parasites, such as pinworms or Giardia.

Look for the cause of an infection, such as bacteria, a fungus, or a virus.

Check for poor absorption of nutrients by the digestive tract (malabsorption syndrome). For this test, all stool is collected over a 72-hour period and then checked for fat (and sometimes for meat fibers). This test is called a 72-hour stool collection or quantitative fecal fat test.

Talk to your doctor about any concerns you have regarding the need for the test, its risks, how it will be done, or what the results will mean. To help you understand the importance of this test, fill out the medical test information form.

3.  Belajar sains terutama bidang perubatan memang menarik dan jika stress [siapa tak stress belajar bidang perubatan yang kebsnyakan kena hafal dan tahu semua istilah], mula mengaitkan semua yang belajar dengan perkara dan benda yang ada di sekeliling. Hasilnya, boleh buat gelak seorang diri sampai tergolek-golek.
