Exercise 22

A correlation exists between a specific gravity by refractometer of 1.050 and a:

A. 2+ glucose

B. 2+ protein

C. First morning specimen

D. Radiographic dye infusion

Step 1 of 2

Terms of specific gravity:

• 1.010-Isothenuric

• Above 1.010-Hypersthenuric

• Below 1.010-hyposthenuric

• Normal specific gravity range is 1.002 – 1.035

• Specimens having 1.002 specific gravity are not urine.

• 1.040 is an abnormal result.

• These results are seen in patient’s undergone intravenous pyelogram.

Intravenous pyelogram:

• It is X-ray examination of kidney bladder and ureter.

• Radio contrast media are the agents used to view the internal structure of the body.

• The agents are barium or iodine compounds.

• These agents are excreted in patient’s urine who have undergone intravenous pyelogram.

• Abnormal results will be seen if the specific gravity is above 1.040.

Therefore, “Radiographic dye infusion” and specific gravity of 1.050 in refractometer has correlation. Hence, the correct answer is option.
