Fever Package - Essential

C-reactive protein (CRP) is a protein produced by the liver that rises in the blood in response to inflammation. A CRP blood test measures these levels to detect acute inflammation, monitor chronic diseases (e.g., arthritis, bowel disease), and evaluate infection. High CRP indicates inflammation, but not its specific cause.

Aspartate Aminotransferase (AST) SGOT - Lab test

Key Details About ALT/SGPT

• Purpose: The test measures the level of ALT in the blood to diagnose liver disease, monitor treatments, and evaluate liver damage.
• Normal Range: While laboratory standards vary, normal ALT levels are generally between 7 to 56 U/L for men and 7 to 45 U/L for women.
• Causes of High Levels: Elevated ALT can be caused by hepatitis, fatty liver disease, cirrhosis, liver infection, or excessive alcohol intake.
• Symptoms of High ALT: High levels may be suggested by fatigue, nausea, jaundice (yellowing skin/eyes), dark urine, or abdominal swelling.

When is the Test Ordered?

Physicians order this test when a patient exhibits symptoms of liver disease or as part of a routine comprehensive metabolic panel (CMP). It is highly specific to the liver, although smaller amounts are found in kidneys, heart, and muscles.

Preparation and Results

• Preparation: No special fasting or preparation is usually required.
• Results: Results are typically available within a few days.
• Interpretation: High levels indicate the liver needs to be investigated, but they do not specifically diagnose the exact cause without further testing.

Platelet Count - Lab test

Key Details About ESR:

• Purpose: Detects and monitors inflammation, rather than diagnosing a specific disease.
• Procedure: A blood sample is taken, usually with no special preparation (no fasting required).
• What it measures: Increased inflammation produces proteins that cause red blood cells to clump together and settle faster.

Reasons for Elevated ESR:

• Infections: Such as pneumonia, bone infections, or systemic infections.
• Autoimmune Disorders: Rheumatoid arthritis, lupus (SLE).
• Chronic Diseases: Kidney disease, cancers.
• Other Factors: Pregnancy and age can also cause higher levels.

Limitations:

• ESR is non-specific; a high ESR does not always mean a severe underlying condition, and a normal ESR does not entirely rule out inflammation.
• It is often used along with other tests, such as C-reactive protein (CRP).

Key Components Evaluated:

• Red Blood Cells (RBCs): Evaluated for size (microcytic/macrocytic), color (hypochromic/normochromic), and shape (poikilocytosis). Key findings include sickle cells, target cells, and schistocytes (fragmented cells).
• White Blood Cells (WBCs): Analyzed for total count, differential count (neutrophils, lymphocytes, monocytes, eosinophils, basophils), and morphology. Immature cells or abnormal shapes indicate conditions like leukemia or infections.
• Platelets: Assessed for number and size; low numbers (thrombocytopenia) or large, abnormal platelets can be identified.

Common Indications for a Peripheral Smear:

• Unexplained Anemia: Determining causes like iron deficiency (hypochromic microcytic) or hemolysis.
• Abnormal CBC Results: Following up on unusual automated counts.
• Suspected Leukemia/Bone Marrow Disorders: Identifying immature or abnormal WBCs.
• Infections: Detecting blood parasites (e.g., Malaria, Babesia).
