Help understanding labs?

My patient has partial duodenal obstruction secondary to pancreatic mass in head of pancreas. She has had bilious vomiting and nausea for 1.5 weeks prior to being admitted. She also has a UTI. All of her labs seem consistent with that to me except that her RBC, hgb and hct are all a little low.

Yesterday they were:

RBC 4.08

Hemoglobin 13.1

Hematocrit 38.3

But today they have all dropped to:

RBC 3.43

Hemoglobin 10.8

Hematocrit 33.2

Ive only ever experienced these drops in a bleed but there are no mentions of bleed anywhere in the chart? I haven't actually met the patient, this is my night before work-up and I'm just wondering if the vomiting could be causing this? If not what could it be?

    there are many factors that you will need to look at. A big one would be....were IVF added or increased? Lab Tests Online: Welcome!

    What happens to your hematocrit when you are dehydrated, as might be expected if you've been vomiting a lot?

    Then what happens when you go to the hospital and somebody plugs an IV into you?

    If you can't find the answer to that, come back and let us know.
