LFT (Liver Function Test)
LFT ya Liver Function Test ek blood test ka panel hai jo aapke liver (jigar) ki sehat jaanchne ke liye kiya jaata hai — isme ek saath 10-12 parameters measure hote hain jaise enzymes, proteins aur bilirubin. Liver hamare body ka sabse bada andar ka organ hai. Ye khaane ko digest karta hai, khoon saaf karta hai, dawa ko process karta hai, aur zaroori proteins banata hai. Agar liver theek se kaam na kare — toh poora body feel karta hai. LFT test basically liver ka "report card" hai. Is test se doctor samajhta hai ki liver ki cells (hepatocytes) theek hain ya damage ho rahi hain, bile (pitt) sahi se flow ho raha hai ya blockage hai, liver proteins banana band kar raha hai ya nahi, aur liver pe koi dawa ya infection ka asar pad raha hai. Ye ek simple blood test hai — ek injection, thoda sa blood, aur 24-48 ghante mein report taiyar. Agar aapke doctor ne "LFT karwa lo" kaha hai — ghabrao mat. Ye test bahut common hai aur aksar routine checkup mein bhi hota hai.
Ye test kab aur kyun karwayein?
Is test se kya pata chalta hai?
LFT test in conditions ka pata lagata hai: Fatty Liver (India mein sabse common, aksar koi symptom nahi pehle), Jaundice (Piliya — bilirubin badh jaata hai), Viral Hepatitis (A, B, ya C), Liver Cirrhosis (liver pe scars), Alcoholic Liver Disease, Bile Duct Blockage (gallstones se), Drug-Induced Liver Injury (TB ki dawayein, long-term painkillers), aur pregnancy mein HELLP syndrome. YAAD RAKHO: Ek akeli abnormal value se diagnosis nahi hoti. Doctor poore panel ko saath mein dekhta hai — pattern matter karta hai, sirf ek number nahi.
Normal range — category wise
| Category | Normal Range | Unit | High → meaning | Low → meaning |
|---|---|---|---|---|
| ALT / SGPT | 7 – 56 | U/L | Liver damage / Hepatitis | Practically concern nahi |
| AST / SGOT | 10 – 40 | U/L | Liver ya muscle damage | Rarely concern |
| ALP (Alkaline Phosphatase) | 40 – 129 | U/L | Bile blockage / Bone disease | Malnutrition |
| GGT (Male) | 11 – 52 | U/L | Alcohol / Liver / Bile duct | Rarely concern |
| GGT (Female) | 7 – 38 | U/L | Alcohol / Liver / Bile duct | Rarely concern |
| Total Bilirubin | 0.3 – 1.2 | mg/dL | Jaundice / Liver damage | Rarely concern |
| Direct Bilirubin | 0.0 – 0.3 | mg/dL | Bile duct blockage | — |
| Indirect Bilirubin | 0.2 – 0.8 | mg/dL | Hemolysis / Liver damage | — |
| Albumin | 3.5 – 5.5 | g/dL | Dehydration | Liver failure / Malnutrition |
| Total Protein | 6.3 – 8.2 | g/dL | Infection / Dehydration | Liver / Kidney disease |
| A/G Ratio | 1.0 – 2.5 | — | — | Liver / Kidney disease |
| PT (Prothrombin Time) | 9.4 – 12.5 | sec | Liver failure / Clotting issue | — |
| INR | 0.8 – 1.2 | ratio | Liver failure / Clotting issue | — |
| ALP — Pregnancy (Normal Rise) | 2x – 4x higher | U/L | Normal — placenta se aata hai | — |
| Albumin — Pregnancy | 2.5 – 4.5 | g/dL | — | Hemodilution — normal hai |
| ALP — Bachche (<18 years) | 100 – 350 | U/L | Normal — haddiyan grow ho rahi hain | — |
Normal range: ALP 2x–4x higher (placenta se — normal hai) | Albumin 2.5–4.5 g/dL (hemodilution se) | GGT 3rd trimester mein lower | Total Bilirubin slightly lower
Pregnancy mein kuch LFT changes bilkul normal hain. ALP automatically 2 se 4 guna badh jaata hai — placenta se extra ALP banta hai, ye liver problem nahi. Albumin thoda kam ho jaata hai kyunki khoon mein paani zyada ho jaata hai (hemodilution) — ye bhi normal hai. GGT teesri trimester mein thoda kam hota hai. Pregnant hone ki baat lab pe ya apni report pe zaroor note karein — doctor already in changes ko jaanta hai aur alag context mein interpret karta hai. Agar in changes ko ignore karein aur normal adult range se compare karein toh galat conclusion nikalega.
Doctor ko kab dikhaye: Piliya (jaundice) ke symptoms aayein, pet mein dard ya itching ho, Pre-eclampsia ya HELLP syndrome ka doubt ho, ya pehle se liver disease ho — tab doctor pregnancy mein LFT likhta hai.
Result ka matlab?
Ghabrao mat — ek abnormal value se koi specific bimari confirm nahi hoti. Intense exercise se bhi AST thoda badh sakta hai. Doctor poora context dekhta hai — akela number nahi. Doctor se consult karo, khud diagnosis mat karo.
Albumin 2.5 g/dL se kam ho — serious liver function loss indicate karta hai, doctor se zaroor milein. Total Protein low + Albumin low — malnutrition ya liver disease ka sign, evaluation zaroori.
Confusion + jaundice + dark urine + sujan — ye combination serious liver failure ka sign hai, turant hospital. ALT 3x normal (120+ U/L) + symptoms — same day consultation zaroori.
Test ki taiyari — best time & tips
Common myths & sach kya hai?
Dusre tests se kya fark hai?
| Parameter | LFT (Liver Function Test) | Ultrasound Abdomen |
|---|---|---|
| LFT blood test hai — liver ke enzymes aur proteins ka level measure karta hai. Ultrasound imaging hai — liver ka size, texture, fatty deposits dikhata hai | ||
| LFT pehla step hai — screening. Ultrasound LFT abnormal aane ke baad kiya jaata hai confirm karne ke liye | ||
| Fasting: LFT ke liye 10-12 ghante, Ultrasound ke liye 6-8 ghante (alag reason se) | ||
| LFT liver damage ka chemical evidence deta hai. Ultrasound structural changes dikhata hai — dono ek doosre ke complementary hain |
| Parameter | LFT (Liver Function Test) | KFT (Kidney Function Test) |
|---|---|---|
| LFT liver (jigar) check karta hai — ALT, AST, ALP, GGT, Bilirubin, Albumin. KFT kidney (gurde) check karta hai — Creatinine, Urea, Uric Acid | ||
| LFT kab: jaundice, fatty liver, hepatitis, liver damage doubt mein. KFT kab: swelling, urine kam aana, kidney disease doubt mein | ||
| Serious illness mein doctor dono saath order karta hai — liver aur kidney dono affected ho sakte hain | ||
| Albumin dono mein common parameter hai — low Albumin liver aur kidney dono problems mein aata hai |
Repeat kab karwayein?
Normal result — aage kab check karein: Koi symptoms nahi: Annual checkup mein dobara. High risk log (alcohol, diabetes, obesity): 6 mahine mein ek baar. Abnormal result: Treatment ya lifestyle change ke baad: 4 se 8 hafte mein repeat. Koi dawa chal rahi ho jo liver affect kare: Har 3 mahine monitor karna common hai. Specific conditions: Fatty Liver diagnosed: Har 6 mahine LFT. Hepatitis B ya C treatment: Har 3 mahine. TB treatment (DOTS): Har 2 mahine mandatory — DOTS protocol mein included hai. Surgery ke baad: Doctor ke schedule ke hisaab se.
Yeh test kin bimariyon mein hota hai?
Homeopathy mein kya?
Ghabrao mat — ek abnormal LFT value zaroor koi serious bimari confirm nahi karti. Report lekar apne doctor se milein — woh poori history dekhkar sahi direction batayenge. Agar LFT baar baar abnormal aa raha hai aur symptoms bhi hain, toh sirf symptom treat karna kaafi nahi — root cause address karna zaroori hai. Homeopathy is approach mein helpful hai — poori health history, lifestyle aur constitution dekhkar individualized treatment di jaati hai jo underlying cause address karne mein kaam aati hai. Side effects practically nil hote hain. Apni report lekar Dr. Shadab Khan se consult karein.
