A stool test checks a small sample of faeces for infection, parasites, hidden blood, digestion problems and inflammation. It is simple, painless and often the fastest way to find the cause of diarrhoea, stomach pain or unexplained anemia. This guide explains the two most common stool tests, the routine stool examination and the fecal occult blood test (FOBT) , how to collect a sample correctly, and what the results mean. Quick answer: A routine stool examination looks at colour, consistency, mucus, blood, pus cells, and eggs or cysts of worms and parasites under the microscope. A fecal occult blood test looks for blood too small to see. The modern immunochemical version (FIT) needs no diet changes and is preferred for bowel cancer screening. Collect the sample in a clean, dry, screw-top container without urine or water, and get it to the lab within about 1 to 2 hours. A positive occult blood test does not mean cancer, but it does need follow-up, usually with a colonoscopy. Key t...

A human chorionic gonadotropin (hCG) urine test is a pregnancy test. A pregnant woman's placenta produces hCG, also called the pregnancy hormone. If you're pregnant, the test can usually detect this hormone in your urine about 10 days after your first missed period. It is often referred to as a home pregnancy test.

Human chorionic gonadotropin (hCG) is a hormone produced by the trophoblast cells that form the placenta after a fertilized egg implants in the uterus. Levels of hCG begin to rise rapidly after conception, doubling approximately every 48 to 72 hours in early pregnancy. This rapid rise makes hCG an excellent early marker for confirming pregnancy. Understanding hCG is also a hot topic in community wellness discussions. You can join conversations about reproductive health and diagnostics at Healthy Living Ideas on Reddit ....

The ESR test (erythrocyte sedimentation rate) measures how fast red blood cells settle to the bottom of a thin tube of blood in one hour. When there is inflammation in the body, proteins in the blood make red cells clump together and fall faster, so the ESR rises. It is a cheap, simple test, but it is non-specific : it shows that something is going on, not what it is. This guide explains the two standard methods, the Westergren and Wintrobe methods, normal values and what high or low results mean. Quick answer: ESR is reported in millimetres per hour (mm/hr). With the Westergren method, a rough upper limit of normal is your age divided by 2 for men, and (age + 10) divided by 2 for women; in young adults it is usually under 15 mm/hr for men and under 20 mm/hr for women. A raised ESR can be caused by infection, autoimmune disease, anemia, pregnancy, kidney disease, some cancers or simply older age, so it is always interpreted with your symptoms and other tests.

Bleeding or pain in early pregnancy is frightening, and it has several possible causes. Two of the most important are ectopic pregnancy , where the pregnancy grows outside the womb, most often in a fallopian tube, and early miscarriage , the loss of a pregnancy before 12 weeks. An ectopic pregnancy can cause life-threatening internal bleeding, so knowing the warning signs matters. This guide explains the symptoms, how doctors tell these conditions apart, and what treatment involves. Quick answer: Ectopic pregnancy affects about 1 to 2 in every 100 pregnancies. Typical signs are one-sided lower abdominal pain, vaginal spotting or bleeding, and a missed period, usually between 4 and 12 weeks. Shoulder-tip pain, fainting or severe pain can mean a rupture and is an emergency. Diagnosis uses a transvaginal ultrasound and blood hCG levels. Early miscarriage is more common, occurring in roughly 10 to 20 in 100 known pregnancies, and usually happens because of chromosome problems in the pr...

Before dipsticks and automated analysers, labs used simple chemical tests to check urine for sugar, ketone bodies and bile. Three of these are still taught in every medical and lab technology course and are used in many smaller labs in India: Benedict's test for sugar, Rothera's test for ketone bodies, and Hay's test for bile salts. This guide explains the principle, procedure and interpretation of each, and how they compare with modern tests. Quick answer: Benedict's test detects reducing sugars (mainly glucose) in urine: the blue reagent turns green, yellow, orange or brick-red depending on how much sugar is present. Rothera's test detects acetone and acetoacetate: a purple-pink ring means ketones are present, as in diabetic ketoacidosis or starvation. Hay's test detects bile salts: sulphur powder sinks instead of floating, which suggests jaundice due to liver disease or blocked bile flow. A positive result is a clue, not a diagnosis, and should be conf...

When a doctor sends urine, pus, sputum, blood or skin scrapings to the microbiology lab, a handful of basic techniques do most of the work: sterilisation with the autoclave , Gram staining , the KOH mount for fungi, culture and sensitivity testing, and quick biochemical tests such as the oxidase test . This guide explains the principle, basic procedure and interpretation of each, for students, lab technicians and curious patients. Quick answer: An autoclave sterilises equipment and media with pressurised steam, typically 121°C at 15 psi for 15 to 20 minutes. Gram staining sorts bacteria into Gram-positive (purple) and Gram-negative (pink). A 10% KOH mount dissolves skin and nail keratin so fungal threads can be seen. Culture grows the organism from a sample, and sensitivity testing shows which antibiotics will work, usually within 48 to 72 hours. The oxidase test turns purple within seconds for bacteria such as Pseudomonas , Neisseria and Vibrio . Key takeaways ✅ Collect sa...

HIV (human immunodeficiency virus) attacks the immune system's CD4 cells. Without treatment it slowly weakens the body's defences until serious infections and cancers develop, the stage called AIDS . Today HIV is a manageable long-term condition: with daily treatment, people with HIV can live a normal lifespan, and once the virus is fully suppressed they do not pass it on through sex. In India, testing and treatment are free through the National AIDS Control Programme. Quick answer: HIV often causes no symptoms for years, so the only way to know is a blood test. Some people get a flu-like illness 2 to 4 weeks after infection. Modern tests detect most infections within about 6 weeks, and a repeat test at 3 months confirms a negative result. HIV is prevented by condoms, never sharing needles, testing in pregnancy, and emergency medicine (PEP) started within 72 hours of an exposure. Treatment (ART) is free and lifelong in India. Key takeaways ✅ Get tested if you have eve...
