A blood test report can look like alphabet soup. Short codes sit next to your numbers. There is no clear meaning in sight. That is why blood test abbreviations trip up so many people.

This guide is a plain glossary. It explains every common abbreviation on a Philippine lab report. It goes one term at a time. Keep it open next to your own results as you read.

Quick answer

The most common panel codes are CBC (complete blood count), CMP (comprehensive metabolic panel), LFT (liver function test), TFT (thyroid function test), and FBS (fasting blood sugar). Common single markers include ALT, AST, TSH, LDL, HDL, HbA1c, and Hgb. Each one is explained below in plain words, grouped by the part of your body it checks.

What do the panel names mean?

CBC: complete blood count

A CBC is a core test. It counts your red cells, white cells, and platelets. Almost every blood panel includes it.

CBC with differential

This is a CBC plus one extra step. It breaks your white cells into five types. Each type fights a different threat.

CMP: comprehensive metabolic panel

A CMP is a wider panel. It checks your blood sugar, kidneys, electrolytes, and liver. It covers about 14 markers in one draw. Many Philippine labs sell this group as a blood chemistry test.

BMP: basic metabolic panel

A BMP is a smaller version of the CMP. It skips liver enzymes and protein. It covers about 8 markers.

LFT: liver function test

An LFT is a group of liver markers. It includes ALT, AST, ALP, bilirubin, albumin, and total protein. Most Philippine lab reports print ALT as SGPT and AST as SGOT. The names differ, but the tests are the same.

TFT: thyroid function test

A TFT checks your thyroid. Your thyroid is a small gland in your neck. It controls your energy. A basic TFT checks TSH alone. A fuller TFT adds Free T4 and Free T3.

RFT: renal function test

"Renal" just means kidney. An RFT checks creatinine, BUN, eGFR, and uric acid.

FBS: fasting blood sugar

FBS is one glucose reading. You take it after 8 to 12 hours without food.

OGTT: oral glucose tolerance test

For this test, you drink a sugary liquid. Your blood sugar is checked at set times after. Doctors use it to diagnose diabetes.

HbA1c: hemoglobin A1c

This is also called glycated hemoglobin. It shows your average blood sugar. The average covers about three months.

Lipid profile or lipid panel

This checks fats linked to cholesterol. It covers total cholesterol, LDL, HDL, and triglycerides.

UA: urinalysis

This is a urine test, not a blood test. It checks your kidneys and bladder. It also looks for infection, sugar, or protein. Labs often order it alongside blood work.

What do the CBC markers mean?

Hgb or Hb: hemoglobin

Hemoglobin is a protein in your red cells. It carries oxygen. A low Hgb often means anemia.

Hct: hematocrit

Hematocrit is a share of your blood. It shows what percent is made of red cells.

RBC: red blood cell count

This is simply your red cell count. It is measured in a set volume of blood.

WBC: white blood cell count

This is your white cell count. It often rises with infection. It falls when your immune system is weak.

MCV: mean corpuscular volume

This is the average size of your red cells. It runs low with iron deficiency. It runs high with a B12 or folate gap.

MCH: mean corpuscular hemoglobin

This is the average hemoglobin amount. It is measured inside each red cell.

MCHC: mean corpuscular hemoglobin concentration

This shows how concentrated that hemoglobin is. It looks at each red cell.

RDW: red cell distribution width

This shows how much your red cells vary in size. It often rises early in a nutrient gap.

Plt: platelets

Platelets are small cell fragments. They help your blood clot.

MPV: mean platelet volume

This is the average size of your platelets.

NLR: neutrophil-to-lymphocyte ratio

This is a calculated score, not a direct test. Doctors use it as a simple inflammation marker.

What do the metabolic markers mean?

Glucose

This is your blood sugar level. It can be taken fasting or at random.

Insulin (fasting)

This is your insulin level after an overnight fast. A high result can mean insulin resistance is starting. That means your body needs more insulin than it should.

HOMA-IR

This is a calculated score. It flags insulin resistance. Doctors get it by combining your glucose and insulin numbers.

Triglycerides (TG)

These are fats that circulate in your blood. They tend to rise with extra carbohydrate intake.

What do the cardiovascular markers mean?

Total cholesterol (TC)

This adds up all the cholesterol in your blood. It counts every particle that carries it.

LDL: low-density lipoprotein cholesterol

This is often called "bad" cholesterol. It can settle inside your artery walls over time.

HDL: high-density lipoprotein cholesterol

This is often called "good" cholesterol. It carries cholesterol back to your liver for removal.

ApoB: apolipoprotein B

ApoB is a small protein. It sits on particles that carry cholesterol. Those particles can build up in your arteries. Many doctors see ApoB as the most accurate heart-risk marker.

Lp(a) or lipoprotein(a)

This is a heart-risk marker set by your genes. You only need to test it once.

hs-CRP: high-sensitivity C-reactive protein

This picks up low-level swelling in your body. It helps predict heart risk over time.

Hcy: homocysteine

This is a small building block of protein, called an amino acid. High levels are linked to heart and brain risk.

NT-proBNP and BNP

These are heart-failure markers. Doctors order them in specific cases, not as routine screening.

What do the liver markers mean?

ALT or SGPT: alanine aminotransferase

ALT (called SGPT on most Philippine lab reports) is an enzyme, or helper protein. It lives mainly in liver cells. It is the marker most sensitive to fatty liver.

AST or SGOT: aspartate aminotransferase

AST (called SGOT on most Philippine lab reports) is a similar enzyme. It lives in your liver and muscles. Doctors often compare AST to ALT for extra clues.

GGT: gamma-glutamyl transferase

GGT is a liver enzyme. It is sensitive to alcohol, some medicines, and bile-flow problems.

ALP: alkaline phosphatase

ALP is an enzyme. It lives in your liver, bones, and bile ducts.

TBili: total bilirubin

Bilirubin is a yellow pigment. It rises with jaundice. Jaundice turns skin and eyes yellow.

DBili: direct bilirubin

This is also called conjugated bilirubin. It points more directly to bile-flow problems.

Albumin (Alb)

Albumin is your main blood protein. It shows how well your liver makes protein.

TP: total protein

This adds up your albumin. It also adds other proteins called globulins.

Codes are easier to read when someone reads them with you. Every marker in your &you Labs panel comes with its full name and a plain explanation.

What do the kidney markers mean?

Creatinine (Cr or Cre)

This is a waste product from your muscles. Your kidneys clear it from your blood.

eGFR: estimated glomerular filtration rate

This is a calculated score. It estimates how well your kidneys filter waste.

BUN: blood urea nitrogen

This is another waste product. It comes from protein breakdown. Your kidneys clear it too.

Uric acid (UA)

This comes from breaking down purines, a substance in some foods. High levels can cause gout.

Cystatin C

This is a kidney marker. It is more sensitive than creatinine alone.

UACR: urine albumin-to-creatinine ratio

This is a urine test, not a blood test. It can catch kidney damage early.

What do electrolyte markers mean?

Na: sodium

Sodium is your main electrolyte outside your cells.

K: potassium

Potassium matters for your heart and muscles.

Cl: chloride

Chloride is a major charged particle in your blood.

HCO3: bicarbonate

This helps keep your blood's acid balance steady.

Ca: calcium

Calcium supports your bones, muscles, and nerves.

Mg: magnesium

Magnesium helps run hundreds of processes in your body.

Ph: phosphorus

Phosphorus supports your bones and your cell energy.

What do the thyroid markers mean?

TSH: thyroid-stimulating hormone

TSH is a brain signal. It tells your thyroid how hard to work.

Free T4 (FT4) or Total T4

This is a thyroid hormone. It acts as a reserve form. Your body converts it when needed.

Free T3 (FT3) or Total T3

This is the active thyroid hormone. It is the one doing the work in your cells.

Reverse T3 (rT3)

This is an inactive form of thyroid hormone.

TPO Ab or Anti-TPO

These are antibodies. They can attack your thyroid. They are linked to Hashimoto's disease, an autoimmune thyroid condition where your immune system attacks its own tissue.

TgAb or Anti-TG

These are antibodies too. They target thyroglobulin, a protein your thyroid uses to make hormone.

TRAb

These antibodies are linked to Graves' disease. That is another autoimmune thyroid condition.

What do the hormone markers mean?

Progesterone (P4)

This hormone rises after ovulation. Doctors check it to confirm ovulation happened.

Testosterone (T)

This is a sex hormone. Both men and women have it.

Free testosterone (FT)

This is the small, active share of your testosterone.

SHBG: sex hormone binding globulin

This protein binds sex hormones in your blood. It affects how much stays free and active.

DHEA-S

This hormone comes from your adrenal glands. It can turn into testosterone or estrogen.

Prolactin (PRL)

This is a pituitary hormone. It is best known for its role in milk production.

Cortisol

This is your main stress hormone.

B12 or vitamin B12

B12 supports your energy, nerves, and red blood cells.

Folate or vitamin B9

Folate supports DNA building. It also supports a process called methylation.

Ferritin

This is your stored iron. Think of it as your iron fuel tank.

Iron (Fe)

This is the iron in your blood right now.

TIBC: total iron-binding capacity

This measures how much iron your blood could carry. Think of it as your iron transport space.

TSAT: transferrin saturation

This is a calculated percent. It shows how full that transport space actually is.

What do inflammation and infection markers mean?

CRP: C-reactive protein

This rises when your body is inflamed.

hs-CRP: high-sensitivity CRP

This is a more sensitive version of CRP. It catches lower-level, chronic inflammation.

ESR: erythrocyte sedimentation rate

Anti-Sm

This antibody is also specific to lupus.

Anti-tTG

This antibody screens for celiac disease, a reaction to gluten.

How do you read a lab report?

A typical report lists the test name, your value, the range, and the units. It may flag a value with an "H" for high or an "L" for low.

Pay attention to any flagged values first. Also watch values sitting near the edge of the range. Check any trend across your past reports too. A group of related markers moving together often tells you more than one flagged value alone.

Standard &you Labs reports pair every code with its full name, so you are never left guessing. You can browse the full biomarker list to see how each one fits into your results.

Frequently asked questions

What does SGPT mean in a blood test?

SGPT is the name most Philippine labs print for ALT, a liver enzyme. SGOT is their name for AST, the other main liver enzyme. Both sit inside liver cells and leak into your blood when the liver is strained. A high result is worth reviewing with your doctor.

What does a high MCV mean?

MCV is the average size of your red blood cells. A high MCV means your red cells are larger than usual. Low vitamin B12 or folate is the most common reason. Regular drinking and a slow thyroid can raise it too.

Why do abbreviations look different between labs?

Lab habits vary a little. Most major codes stay standard worldwide. If you are unsure, look up the full test name or ask your lab.

Are these abbreviations the same in Philippine labs?

Largely, yes. International lab standards are widely used here. Local labs keep a few names of their own. They print SGPT for ALT and SGOT for AST, and they often sell a CMP as a blood chemistry test.

What if my report has a code I do not recognize?

Check the lab's own glossary. You can also search a trusted medical site or ask your doctor. You do not need to guess.

Should I memorize all of these?

No. Knowing the major ones helps you read reports faster. For markers you track closely, depth matters more than covering every code.

Will my &you Labs report explain each marker?

Yes. Every value in a &you Labs report comes with its full name, a short description, and what it means for you.
