How many drinks does a peth blood alcohol test detect?

That hasn't been clearly defined. Some estimate that PEth (phosphatidylethanol) becomes positive around 84 g (approx 6 drinks) of consumption, others claim closer to 200 g (approx 14 drinks). Both measured by pure alcohol at 14 g per drink.

Suffice to say that PEth becomes positive only after drinking on 6 or more sequential days, little as one drink per day, or by binge drinking on a single day.

Although the test is already in use by a couple of laboratories there is much more that needs to be clarified.

Since it requires a blood draw it is unlikely that the test will replace EtG/EtS testing.

ERC stands for erythrocyte count (red blood cell count). It tells you the the number of RBCs that are present in blood. Low values are indicative of anemia. ERC is also closely related to hemoglobin (Hgb) and hematocrit (Hct) levels; if the ERC is low then Hbg and Hct will most likely be low. ERC is usually measured with the complete blood count test (CBC).
