Which of the following values ​​is most reliable for identifying anemia in animals?
A
RBC count
B
Hemoglobin concentration
C
Hematocrit
D
Packed cell volume
Explanation: 

Detailed explanation-1: -Anaemia is most simply and reliably estimated by measuring PCV percent using the haematocrit method, whilst determining the Hb concentration gives accurate information on the type of anaemia (Murray et al. 1983).

Detailed explanation-2: -There are several tests that are performed on the blood sample to diagnose anemia. The most common test is the packed cell volume (PCV) or hematocrit (HCT). These tests are often performed as part of a complete blood cell count (CBC). In a normal dog, 35% to 55% of the blood will be red blood cells.

Detailed explanation-3: -Published data from Europe and North America indicate that for non-iron-deficient adult Caucasian males, the normal mean packed cell volume (PCV) is 0.46 and the 2.5-97.5 percentile interval is 04.0-0.53. Corresponding values for adult Caucasian females are: mean PCV 0.42; 2.5-97.5 percentile interval 0.36-0.48.

Detailed explanation-4: -Symptoms of iron-deficiency anemia are related to decreased oxygen delivery to the entire body and may include: Being pale or having yellow “sallow” skin. Unexplained fatigue or lack of energy. Shortness of breath or chest pain, especially with activity.
