Hello and welcome to Healthcare Magic.
There is no medical term in a urinanalysis as "ublood". Have you misspelled the word or entered some abbreviated form of the word?
But to clarify your basic doubt, whether there is a difference between detecting RBCs and detecting "blood" in a urine test, the answer is yes. Here's the difference:
- Most urine tests detect the presence of RBC (red blood cells) through a microscopic examination. Now, presence of RBCs in the urine (known as "Hematuria") simply means that there is bleeding somewhere in the urinary tract
- could be due to an infection or stone or injury
or a bleeding disorder
- Some urine tests (especially the urine dipsticks) detect the presence of blood through the detection of hemoglobin
(a protein which is the most important component of RBCs (red blood cells). The presence of hemoglobin in urine is called "Hemoglobinuria". The significance of hemoglobinuria is that it indicates that the RBCs have lysed or destroyed in the vascular system itself (called "Hemolysis"), thereby releasing the hemoglobin - which is excreted in the urine and detected as "blood". So, technically, there can be blood in urine without the presence of RBCs.
I hope I have clarified your doubt.
