Red Blood Cell Morphology with Urine Analysis (Comprehensive Hematologic and Urinalysis Profile)
This test evaluates the shape, size, and health of red blood cells (RBCs) and checks urine for signs of infection, kidney issues, or other conditions.
["It helps diagnose and monitor blood disorders and kidney or urinary tract problems."]

What This Test Measures
The test includes a detailed examination of red blood cells (RBCs) for abnormalities such as shape (e.g., spherocytes, elliptocytes), size (microcytes, macrocytes), and signs of damage or destruction. It also assesses the presence of certain cells like reticulocytes, which indicate RBC production or breakdown. Additionally, urine analysis checks for protein, blood, glucose, ketones, and microscopic particles like red blood cells or white blood cells, which can signal kidney problems or infections.
Why It’s Done
Doctors order this test to diagnose conditions like anemia, blood disorders (e.g., thalassemia, sickle cell disease), kidney disease, urinary tract infections, or other systemic illnesses. It may also be used for routine health checks or to monitor ongoing treatments.
Common Conditions It Helps Identify
Red blood cell morphology can reveal issues like iron deficiency anemia (small, pale RBCs), hemolytic anemia (fragmented RBCs), or conditions like sickle cell disease (abnormal shapes). Urine analysis can detect kidney damage (proteinuria), urinary tract infections (leukocytes), or diabetes (glucose).
Sample Collection and Preparation
For RBC morphology, a small blood sample is drawn from your arm. For urine analysis, you may provide a midstream urine sample or a 24-hour urine collection, depending on the test requirements. Your healthcare provider will explain the process and any preparation needed.
Reference range
Adult males: 4.2-5.9; Females: 3.8-5.1 x 10^12/LN/A
No special preparation required. Stay well hydrated.
